After setting up new user, was checking notifications. Noticed two things:
1) Don’t seem to be getting phone text message notices, either him or me. I hadn’t noticed before. Am getting app-pushes and email notices, but texts don’t seem to be arriving (not in spam either). I know some ISPs block auto-generated messages, so this might be something to do with that, so hard to tell if a bug or not.
2) App pushes only seem to arrive when phone is connected to wifi. If phone is on cellular service only, we don’t seem to get them. My phone is always connected to wifi where ever it is, so I never noticed this. This particular user is a bit paranoid about hacking and surveillance, so never connects his phone to wifi network, even in his own house, only uses cellular service.
