I’m from Graz/Austria and I received my FP2 1.5 week agon.
I switched to FP Open 16.12.0 but I also installed Google Play Store. I know, not everybody thinks this make sense
I also installed Xposed, Xprivacy and AFWall+. It was a lot of work, but I managed it.
Now everything allmost works fine. There is only one issue with missed calls. I made a support request and I will do an forum-post.
The company I working for allowed that I chose the phone für me. So I decided for Fairphone, because it is very important for me to support the things Fairphone stands for.
