Anki keeps remind me to Check Database

[isudfv]

I mainly add cards to my deck with Anki and memorize them with Ankidroid.

But once a while Anki complains "please use the Check Database function, then sync again. If problems persist, please force a full sync in the preferences screen".

And I've fullly synced a million times. What caused the problem?

Could you lell me te anki version ?

[isudfv]

Anki Version ⁨2.1.49 (dc80804a)⁩ Ankidroid 2.9.1 And anki-sync-server is latest release

I havent encountered your problem on Anki 2.1.50(beta). Can you trproduce this from scratch? As detailed as prssible

[isudfv]

it seems sync on Ankidroid caused this problem. Once there's a sync from Ankidroid, the "check database" error pops up. Adding a card on Anki also causes the problem even though there's nothing from Ankidroid. But everything on Ankidroid is fine.

If possible,Could you record every step you take in detail with 1....2....3.... ? With new created user and empty anki clients.

1. create user test
2. login with test on Ankidroid and Anki
3. sync on Ankidroid(upload everything from Ankidroid to server)
4. add my previous deck exported from Ankidroid(there is a V2 scheduler problem when exporting, I thought that's it, but the error persist after switching to v1)
5. sync and everything is fine with user test

[isudfv]

I tried delete my user and start over.

1. delete isudfv with anki-sync-server
2. delete isudfv in src/collections/
3. add isudfv
4. sync from ankidroid
5. download from web on Anki
6. everything is fine so far
7. modify something on ankidroid and sync
8. "check database"

Ankidroid(there is a V2 scheduler problem when exporting, I thought that's it, but the error persist after switching to v1)

How about updating ankidroid version above 2.9.5 and retrying?

[isudfv]
