Does it also happen in the desktop version?

What are the steps to reproduce this bug?

I installed Anki 25.07.3, configured it, created decks, synced it with AnkiWeb, installed AnkiDroid 2.21.1, gave it all permisions, loged in to AnkiWeb, and typed the sync button at the top right corner

Expected behaviour

The notification above shouldn't appear at all

Any workaround in the meantime? Not able to use ankidroid at all because sync from ankidroid to server dosent work at all.

[david-allison]
