Questions about installing apps from owner profile to secondary profiles

ham

If I install an app from the google play store onto the owner profile then copy that app to the secondary profile by installing it from available apps how does the app in the second profile update if I don't have google play services installed on the second profile? Does it update whenever the app in the owner profile updates? Also, will the app in the second profile receive notifications (assuming it depends on google services) or would I need to still install google play services in the second profile as well?

On a side note, is it safe to use profiles now? I had heard there was a bug resulting in data loss but wasn't sure how common it was.

ham If an app needs Google services (for, e.g., notifications) then the Google infrastructure must be installed in the same profile as the app -- profiles are for isolation, so if the Google infrastructure is in a different profile it's unreachable.

Each app is installed just once, so if the owner profile updates it then it is updated for all profiles.

It appears that AOSP and Google's Pixel OS had a data-loss bug related to profiles, but I don't think GrapheneOS does. GrapheneOS user are reporting UI stalls and fingerprint issues related to switching profiles. Some GrapheneOS users are reporting data losses that sound plausibly related to running out of battery power during a system update.

Yes. App updates apply cross-profiles.

Edit- this question was already answered above, I missed it.
