I was able to make a purchase using the sandbox user. However the "Use real Bitcoin (mainnet)" dialog doesn't close when the purchase is complete.

• [x] Close the dialog when user make payment e0e0df0954f5255593e98049c4503991701b631c

I also suggest making the "Subscribe Now" button grey while the purchase is in progress.

• [x] Change UI color 0c9ed453b193eee46084dd2604b3cb53620ba0ec

I see, but a month is not 30 days, so that bit has to be more accurate. Right, so we just check if: current time > expirationDateFromResponse (stored in UserDefaults)

• [x] check current calendar and set the date according to it 258c96ba3825480d9634c7de48b5feb8ae18e028
• [x] Ask status after this date da8f237939cca662cbbe9d93e51e3798d1c3474f

So we do something like this?

1. When user makes a purchase, store the expiration date
2. When app wakes up check if time > expiration date
3. When time > experitation date, fetch (???) from Apple: a) update expiration date (??) b) turn off subscription if it wasn't renewed (if connection to Apple fails, just ignore and try later)

Only minor suggestion (can wait): when the purchase (or restore) is complete, jump to the mainnet tab. If it's easier: do this for both the Announce and Import sections.

• [x] mark requested tab after purchase 1cc14fb0378f6e7b0f25ac221101160de9ebf97c

When the user does not have a subscription and they airdrop (or open via files) a transaction, make sure the sign button is also disabled and the user is prompted to subscribe.

@Sjors Based on the current implementation user should have an active subscription to load or scan mainnet's PSBT.

So, we overview the next case: user open import dialog and after that the subscription isn't active anymore. User can load psbt but the app should not allow to sign without active subscription. Just clearify the case.

[Sjors]

When there is no subscription, it should not process or show the PSBT (not a high priority issue though).
