Issues with Apps after update to Open OS 18.10.0 (Android 7 Nougat)

Nobody?

Another question; is it possible to install just google maps and nothing else of gapps? (no services etc) Is there a more detailed howto available than Android Auto (and Google Maps) on Fairphone Open ? Thanks.

edit: Even though I still think modifying the apk to not use google stuff anymore by just deactivating it is the most sensible and fairphone-ish way to solve that issue (actually there was a nice solution in the past for blackberry; Play Services Patcher formerly GMaps Patcher) I gave up and tried to install microG (in order to install google maps as briefly described in the first link). The result was that Greenify immediately crashed and Sophos a few seconds later… so now I don’t have any further ideas… (I don’t want to have to return to Fairphone OS honestly…)
