I just upgraded my Galaxy S5 (G900A) to Marshmallow 6.0.1., from Lollipop. The default app functionality from Lollipop seems to be broken in marshmallow. I've tried making Poweramp the default app in app manager and default apps without success. The default apps list does not have Poweramp listed. I disabled Google play music. There's also a "music" app which cannot be disabled. Nothing has worked. Is there a limitation or bug in Marshmallow? Your help is appreciated.
Edit: I messed around with mx player permissions and I was able to choose it as default for my video player. So far no su
