Can’t import files on RPi 5

I’m unable to import .xmls, images, .rd files, or anything on RealDash on my RPi 5 running Linux. When you hit the “+” to import files it doesn’t open the file manager to add anything. I tried working around this by editing the .rd on my iPad and uploading it to my RealDash account, then importing it from my account on the Pi, which works (albeit with the resolution change issue), but doesn’t actually save or overwrite the .rd file - it disappears again after closing the app or exiting to the gallery.

Is this a bug or Linux limitation? Any other workarounds?

The standard Linux open file dialog should pop up. Are you using a standard, non-modified Linux desktop distro?
