Apps cannot access SD card

[iw250]

The SD card on my XZ1c can be used for storing camera pictures. But other apps are having problems. For example, I cannot get OsmAnd to store maps on the SD card. I get the following error:

11-07 09:18:39.414 20119 20119 W net.osmand.plus: type=1400 audit(0.0:205941): avc: denied { create } for comm=4173796E635461736B20233130 name="tiles" scontext=u:r:untrusted_app_25:s0:c512,c768 tcontext=u:object_r:ecryptfs:s0:c512,c768 tclass=dir permissive=0 ppid=766 pcomm="main" pgid=20119 pgcomm="net.osmand.plus"

This points to SELinux. I already tried a reformat. Encryption is off. Is this a known problem on this device? I did see some similar threads for other devices...

Any hints are welcome!

Have you tried a reset of the device?

There is definitely something wrong with permissions if Google maps cannot save offline to SD

Same problem her, Google Maps detects the SD-Card (extern!) but can't write on it.

Google Pictures - fine, Sony Cam - fine .....

Deleting data/cache doesn't help.

Reinstallation neither.

A few other navigation apps have the same problem.

OruxMaps can write on the SD-Card.

I don't know if this post anyone helps. I have had same problem on Xperia X compact after upgrade from Nouget to Oreo. It seems this upgrades never works fine. So I did factory reset and now works. There are 3 types of reset and I suggest always when you make major upgrade that you are ready to do factory reset.

Hope this helps.
