Hello, Using Android 9 (Hardware is Retroid Pocket 2+) with latest Retroarch (x64 stable 1.10.3).
When changing the default directory of Save States to a folder on an SD Card (formatted to FAT32), RA will fail to write save states. This has been a bug for many versions now. RA is able to navigate to the SD card and read the save states on the SD card without issue - issue is only when writing. When manually trying to save a state, will see the notification for “Save state 0%” - and it will stay stuck indefinitely.
