I've been using vgbanext for quite a while. It worked perfectly.
Since yesterday, I found it wouldn't create .sav file anymore. Right now, if I load a new game, it won't create the .sav after quitting, but quick save/load can still work, and screenshot can still be created in the folder.
If I load a game already with old .sav file, it can be loaded correctly, and I can see my in game save. However, after playing for a while, saving, and then quitting. The .sav won't be updated. I opened the game again and my game started at the old place.
I don't know what causes this problem. I re-installed vgbanext from play store and re-grant storage access. No luck.
Vgbanext in my other phones work fine.
This happened since few days ago, on my Nokia 8.1, android 10.
Thanks in advance for any help.
