puzzles are not synchron on different devices

I play lichess on different devices. I play it on pc in my Firefox browser, on my smartphone and tablet (Apple each) using the lichess app.

When i change the device after solving some puzzles, i get the same puzzles (unrated however) again.

My puzzle status (rating and solved puzzles) seem not beeing synchronized, although i play on the same account.

How can i fix that?
Sometimes i‘d like to switch from pc to tablet and from that to Smartphone and just go on ...

I have the same experience, though honestly repeating puzzles are helpful in sticking the patterns to memory. I wish they were a legit feature.

@CtripleA I agree, I have exactly the same experiance...
