Texture export on Android -- can't seem to change path or locate exported files!

[plorry]

Tablet is Samsung Galaxy Tab 4, Android Version 10.

Just bought ArmorPaint, and have created a texture for a model I successfully loaded from my device, but going to "export texture", and setting "Disk" as the destination, I'm presented with a "browser" pop-up, only... there's no clear indication of what the path is. All I see is a single folder labelled .. (the "up one directory" folder). I can't navigate anywhere on the device, and if I type in a name and hit save, the console log says that it exported the texture, but I can't locate it anywhere. I've searched my device, manually, and by filename; the exported file, with the name I've given it, or any other name, can't be found anywhere. I've also tried manually entering in a path on the device, since I can't navigate; this also came up negative.

Is there some known issue here, or am I missing something about where these exported image files are going?
