Does it also happen in the desktop version?

What are the steps to reproduce this bug?

Have deck with multiple subdecks
Increase new card limit in each (parent+child)
Increase new card limit in parent deck

This is confusing so I'll try to get a recording

Here's the video

I broke down the video in steps and made tables showing the relevant changes. What I found out is that you should have increased the child decks again in order to get more cards.

I came up with some terminology.

H = Hungry (wants more cards) E = Exhausted (does not want more cards)

A deck being hungry means that the deck's limit allow for more cards, but the deck is limited by its parent. A parent deck can never be hungry. A deck being exhausted just means that it is not hungry. The deck's limit is utilized to its full potential.

I will call your decks just by alphabetic letters and numbers. Decks C1, C2, C6 and other decks I excluded are not relevant to the demonstration.

Initial state

DECK        ACTION  CHANGE  STATE   NEW CARDS
A           -       -         E       0
A::B        -       -         E       0
A::B::C3    -       -         E       0
A::B::C4    -       -         H       0
A::B::C5    -       -         H       0

--

Step 1 (0:00 - 0:09)

DECK        ACTION  CHANGE  STATE   NEW CARDS
A           +2      +2        E     0→2
A::B        -       -         E       0
A::B::C3    -       -         E       0
A::B::C4    -       -         H       0
A::B::C5    -       -         H       0

Notes

The fact that B didn't get any new cards indicates that either it or all of its childs (or both) are exhausted.

--

Step 2 (0:09 - 0:16)

DECK        ACTION  CHANGE  STATE   NEW CARDS
A           -       +2        E     2→4
A::B        +2      +2        E     0→2
A::B::C3    -       -         E       0
A::B::C4    -       +2        H     0→2
A::B::C5    -       +2        H     0→2

Notes

Why did A get new cards if A was exhausted? I guess you do not have "Limits start from top" enabled. Which I guess means, that when you increase the limit of a child deck, parent decks also have their limit increased. If you do have that option enabled, then it does not work the same as on my device (in fact, it works in a better way for you). However, I don't know if my analysis makes sense if you do not have that option disabled...
C3 not getting any new cards here means it was exhausted.
C4 and C5 getting new cards here means it they were hungry.
C>B means B was exhausted.

--

Step 3 (0:16 - 0:21)

DECK        ACTION  CHANGE  STATE   NEW CARDS
A           -       +2        E     4→6
A::B        -       +2        E     2→4
A::B::C3    +2      +2        E     0→2
A::B::C4    -       +2      H→E     2→4
A::B::C5    -       +2      H→E     2→4

Notes

Again, the limit of the parent decks A and B are for some reason increased when you increase a child deck.
As a result of A and B increasing, C4 and C5 also increases.
C4 and C5 getting new cards means they were hungry.

--

Step 4 (0:21 - 0:28)

DECK        ACTION  CHANGE  STATE   NEW CARDS
A           +2      +2        E     6→8
A::B        -       -         E       4
A::B::C1    -       -         E       2
A::B::C3    -       -         E       2
A::B::C4    -       -         E       4
A::B::C5    -       -         E       4

Notes

B and C not getting any new cards here means they were exhausted.

--

Step 5 (0:28 - 0:32)

DECK        ACTION  CHANGE  STATE   NEW CARDS
A           +2      +1        E     8→9
A::B        -       -         E       4
A::B::C1    -       -         E       2
A::B::C3    -       -         E       2
A::B::C4    -       -         E       4

Notes

I assume you do not have any more cards in A, which is why you only get one new A card. If you're confused, it might be that you have added cards to that deck on accident.
B and C are exhausted, which is why you do not get any more B or C cards. You need to increase their limit if you want more.

--

Step 6 (0:32 - 0:38)

DECK        ACTION  CHANGE  STATE   NEW CARDS
A           +2      -         E       9
A::B        -       -         E       4
A::B::C1    -       -         E       2
A::B::C3    -       -         E       2
A::B::C4    -       -         E       4

Notes

Nothing happens because you are out of cards in A; while B and C are exhausted.

--

Step 7 (0:38 - 0:46)

DECK        ACTION  CHANGE  STATE   NEW CARDS
A           +2      -         E       9
A::B        -       -         E       4
A::B::C1    -       -         E       2
A::B::C3    -       -         E       2
A::B::C4    -       -         E       4

Notes

Nothing happens because you are out of cards in A; while B and C are exhausted.

Some way of identifying hungry decks might be nice. Maybe they could be grayed out, meaning "sorry buddy, I know you want more, but you will have to wait until tomorrow." It would also be nice to be able to see exactly how hungry a deck is, i.e. how many cards below the limit the deck is. Maybe. I need to take a break from this now.
