I installed it on my Fairephone4. Have to say i'm pretty impressed, everything works fine including maps and bank application. They really managed microG well.
The only probleme I got in the last 6 month is that I can't installe paying app on my phone. I created a google account to connect to the app store but the page to pay just never load. That's not a big deal for me anyway.
I recommend if your phone is compatible.
I've exactly the same problem since yesterday. Didn't search for a solution, i usually just wait for next release when problems like this appears.
