Anders_ASUSIt's possible, but that might have been due to another issue: a month ago it didn't work at all for a while, but an update fixed that. And scrobbling always seemed problematic - on my previous phones (and this one as well, I think) I had issue with the official last.fm app, which is why I'm using this alternative one in the first place.
I wish I could say what is wrong. So your issues are with Strava and Simple Scrobbler? A lot of users doesn't seem to be happy with Simple Scrobbler when reading the reviews at play store. May it's the app that can't maintain accessibility?
