Locus Pro without Google
is there any possibility to get Locus Map Pro running without Google Services? I purchased this great app via Playstore but now I want to get rid of Google. But as I can't live without some functions I'm using microg (use some Google functions without actually sending too much to them). I tried to install Locus via Yelp (Playstore Clone) and my own Google Account, but can't Locus get starting. In the initializing screen I get the 1811 error (can't find what it means). I see that the missing Google services is the problem.
So is there any other way to get it working? I mean besides Amazon? As I don't want to use their services either.
