Anki app error message

When I try to sync my laptop to my phone, I get this error message. Does anyone know what that means and what I can do about it?

Thank you!


Please tap on the gear/cog in the top right, then “check database”

Thank you! I tried that and it initially stated that I should reposition my cards into the browser (or something similar) and then I tried to sync again and checked datatbase and now it says “ Database rebuilt and optimized.” but I still get the same error message

Hmm. Ok, please force a one-way sync in the preferences screen. If your phone has your latest data, please choose upload, and then download on your other devices. Does that resolve the issue?

Thanks so much. Had to force a one way sync and it worked.
