Writing this topic as I’m seeing it.
I haven’t tried to reproduce it in a different context.
Nevertheless, error screen pops up each time but in the end it always access to the folder.
simple step by step is:
1- go to a folder at the root
2- play sample with enter
3- long press F5 to go to preview setting
4- press back
5- try to go again in the previous folder
6- error screen appears
7- wait until it disappears and it goes inside the folder
8- repeat from step 2
bonus question: in the above scenario is there a shortcut or a key to go back to the previous folder instead of the SD card root when pressing Back?
Update:
Graphic glitch when pressing shift+back in the preview sound screen then scrolling with the encoder.
Another graphic glitch? when messing with output channel, run/stop and back in the preview sound window. I guess it was already reported but it seems that the sample only plays on the left side.
