Why is duolingo not synced on my pc and phone?
Just did a few hours work on my pc, went to my phone and it's way behind!
Usually whenever I get on a different system but same account, I will do a refresh to make sure I am looking at the latest information. Without refreshing you may be looking at a cached version. On PC, hit the circular arrow button to refresh. On the app, drag the screen to the top, then drag further to cause a refresh. That should sync up the two.
