Location in Android apps

Swiss Rail’s SBB Mobile I can load, but after start the app informs Location not found or insufficient. Which is a pity as SBB mobile would detect and bill the correct fare based on location information. Other location using Adroid stuff, like Osmand, work very well. So, what could be the reason? (Got no play store, only microG which seems running but only half (no correct play store signature))


I would like to ask how to use UBER in SFOS. It doesn’t work either
