Harvey,Because a lot proprietary apps are 'looking' for GmsCore. If they don't find you get an error message: google play services missing'.
Best sample, banking apps or Protonmail. But now GmsCore (microG) is available and apps are working![]()
Is it possible with your GSI to run Open Street Map inside apps like this using MicroG or this is no private?
