[deleted] thanks for your help. I installed Google Services, location right now is obviously spot on which was very important for me. It makes my life so much easier when I travel. I really need that.
I reinstalled all the apps from the play store that didn't have a github release apk (obtanium) and now everything is working fine so far. I will test it on mobile data.
I appreciate your help, privacy is important to me but functionality is more important. I guess I could have created another user profile but too much trouble. With Scopes and permissions I can limit pretty well what to share and since I have to use Whatsapp, Spotify and Instagram no matter what (fake accounts all of them), this is the best I can do.
Last question, Play Store asks for an update of itself. I didn't do it because I thought GrapheneOS Apps should do that.
