Having same issue.
I am also having the same issue. Any help would be so grateful. I have about 6000 cards that i need to get through this month and everday I do about 1000+ and my mobile never syncs with my desktop version and now my desktop version somehow reset itself. I have no idea what is going on, please advise
Also I see that my desktop anki is syncing properly to my ankiweb, but it does not sync properly to my anki mobile. My anki mobile has way more cards for review.
In addition, I do see that on my desktop I have anki scheduler 2.1 scheduler enabled. I am not sure if that is causing the issue?
