de0u I think it is the way it is worded, that can be read in two ways.
"By using a separate profile you can select which apps use Google Play Services", I took it to mean you could select in that profile which apps allowed Google Play Services.
What they mean, is you can select which apps use Google Play Services, by putting the apps you want to use it, in a separate profile running Google Play Services.
A little bit ambiguous.
Anyway in the profile I have Google Play services, the email apps which were warning me about not working properly as they didn't have access to Google Play Services, are not warning me of that since I installed it, but I am still not getting notifications.
Do I need to uninstall and reinstall all the apps that need Google Play Services to run fully?
