Using Syncthing app v0.7.21 and Syncthing 0.13.10 Win x64 both current as of post. Syncthing works perfectly between my desktop PC and laptop, and kind of between phone (Galaxy S5 not rooted). The issue seems to be it's only syncing one level deep on my SD Card, the app does have full permissions as required, here are a couple screenshots:
Pic 1 for the top two folders, Phone-pictures synced though it stays at 99% now and the desktop Syncthing shows "syncing 100%" on the device.
Pic 2 when I go to folder picker adding a new folder, I get that error. Again I did give permissions to the app, it did sync the Phone-pictures, but any time I go more than one level deep (you can see the Phone-pictures is in the root of the SD card, not a subfolder of a root folder).
Appreciate any help as I love this software but can't get this figured out, cheers!
