Unable to save data

[Javtor]

I'm using ppsspp 1.17.1 as a core in retroarch for ios.

Every time it try to create or write saved data in the memory stick (SAVEDATA folder) it indicates that it is not possible. I even tried to import data in SAVEDATA created in an android version and it can't overwrite it.

The problem happens in all games and the save states work ok.

Any suggestions? Is there a fix? Thank you!
