When I press the folder, nothing really happens.

Can't seem to reproduce it on my machine, what's your distro?

[alexanderschuman144-afk]

Debian. I also tried it on Android from F-Droid, and it does the same thing too.

Can you try out the latest development build?

On Linux, the app uses either kdialog or zenity (both may be unavailable supposedly?), now I also enabled a non-native file chooser as a fallback.

On Android, not even sure what to guess, it works on all my devices, maybe it's a permissions issue, or the button is too small and easy to mistap? Made the button area larger just in case, and added a popup about lacking permissions in the development build.
