Dumdum No. Contact lists are separate.
Is there any secure/privacy way around it?
If for instance I have contact1 and contact2 under my user1 profile and I'll install WhatsApp under user2 and only contact3 and contact4 will be under user2 profile, it would mean I won't be able to conveniently get phone calls from the contact list of user1 while under user2 and vice versa.
There must be a way.
Dumdum User profiles have the setting "Send notification to current user" which can be enabled per-profile. If you want to have notifications from User1 while Owner or User2 is active, then you must turn this setting on for User1.
I knew I missed something like that, thanks!
Does it affect/reduce security in anyway please?
fid02 Play services also has other features that don't require a Google account, such as support for security keys
What does it mean please? Can you provide an example?
fid02 It doesn't make anything more secure. It just makes people feel better by thinking that they are minimizing the data that Google collects from their app usage. Lots of apps contain Google proprietary blobs so in practice there is still plenty of opportunity for app usage data collection, even if you downloaded the apps from an alternative app store.
Dumdum If you're using the "Anonymous login", yes. You can choose (for little to no real benefit) to use Aurora with your own account. As for the followup to this question, I wouldn't be able to tell you.
Okey, but what is the connection between the account(real or fake) and the app itself, is there any connection between them or perhaps it's not known yet?
Because if it's some application like Instagram, I would want to tie it to my real user account, because it's part of my real life and I don't want any fake Google accounts to interfere. Or am I getting this wrong?
