content items are not displayed - car sharing etc

During the last half year, some apps changed from "working with (severe) flaws" to "not delivering the contents desired."

Prominent examples are
free2move - car sharing umbrella app for various companies
Deutsche Post
ofo bike sharing

They have in common that everything works fine - exept the target contents (e.g. vehicles to share or letter boxes) are not displayed in the maps - and so the app cannot be used. To me as a layman it looks as if g**gl introduced a new mechanism of displaying objects recently which microG has not yet implemented. A years ago the 2 apps mentioned above worked, allthough not flawlessly with microG.

Other similar apps still are working, such as
Drive Now car sharing
car2go car sharing
lime bike sharing
mobike bike sharing

Car sharing is a key feature to me - so I'd say fixing this is urgent.
I'm using most recent microG version 0.2.6.13280 on lineageOS 14.1-20180524.

Start by reproducing the missing map content with the listed free2move, Deutsche Post, and ofo apps on the reported microG and LineageOS versions, then compare them with the working apps. Done means the target vehicles or letter boxes are displayed and usable in the maps.
