Number of Studied Cards Is Not Synced to Other Devices

When I study, say 50 cards on my PC, sync it before closing the window and then continue to study more cards on my phone, then it tells me that I haven’t studied any cards that day. So if I want to hit my daily targt of 70 cards I have to start all over to reach that number of studied cards instead of continuing at 50 studied cards.

Does anyone know the problem?
Does anyone know a solution to this problem?

Thanks in advance!

The solution was to simply log out and log in again… Sorry, I could have thought of this earlier :see_no_evil:
