Some apps cannot read external SD

[lebochequirit]

LOS 14.1-20171010-NIHGTLY-gohan
Installed, runs stable and nicely. I'm very happy with it.

My Issues: Filemanager can read from and write to external SD card.
Locus Pro did detect the files on the external SD and complained not being able to write to it (which I consider normal *sigh). Copied the Files, then Locus did not DETECT the files on external SD any more.
LOS Gallery neither detect the folders on the sd card, nor can it be pointed to the folders manually. Same with other gallery apps like LeafPic or the gallery app from f-droid.

QuickPic (which offers extended folder selection and exclusion) shows the folders on SD and detected them automatically.
Vanilla music did not automatically detect music folders on the sd card, but could set to read them manually (and does so).

Though I'm fine with vanilla music and QuickPic for the moment, I'd suggest to have a look into the problem for it may be some permissions thing leading to real problems somewhere else.
Also enhancing the LOS-shipped gallery app by a folder selection option might be an idea, if that's your business at all.

Thanks for all the effort you put in this, I read the forum thread on the projects' status and think you few guys really nailed it.

Can anyone reproduce this? I don't have an external SD card in my test device right now...
