Tactics stuck on same puzzle

Hello, the tactics are stuck on the same puzzle. . I tried clearing data and cache. Still goes back to the same puzzle. I clear the puzzle and then when it should go to next puzzle, instead - it starts same puzzle over and over again...

Please help!

I love the tactics (I used to, anyway)

Thanks.

well that is really weird

Well thats strange, you mean that you complete the puzzle positively and go to the next one and it shows the same?
In case you didnt succeed in completing a puzzle it will show the same but only after 20-50 more other puzzles

Which is the address of the puzzle? the URL: lichess.org/training/ and what is next? Can you share it?
Is it the mobile app?

I can offer to test what happens just if you change, enumerate, the numbers in the address:

lichess.org/training/93183
lichess.org/training/93184
lichess.org/training/93185

It could be a workaround or a nice test
