Hello.
I have been using Mnemosyne for quite a while now (years I suppose) and so far most things have been fine.
But right now I am running against a wall with a "problem with latex. are latex and dvipng installed"-issue.
Background:
I switched to a new phone (jumped from Android 8 to 13). Old phone was working fine (it worked in conjunction with 2.6 of the Desktop version of Mnemosyne).
On the new phone I installed Mnemosyne using the Play Store and immediately tried to sync (with 2.6 desktop). Did not work out too well -> so I upgraded to 2.9 of the Desktop version. Now the sync worked, but latex cards did not work.
I "fixed" the issue but reinstalling the app on the phone, restarting the phone and resyncing. I could now do repetitions, including latex-cards.
Next day ...
Latex cards show the error again. Solution: Sync current progress to desktop, delete app files, resync. Cards work now.
Next days ...
Same issue again and again. Not just cards that had no repetitions on the new phone, as of today also a card that worked yesterday (after the whole delete and resync).
Someone an idea what the issue might be?
