Apple caused this issue 

Yes you can still zap but you zap the profile, not note specific unfortunately. This goes for all iOS nostr apps

Primal only gets "around" this because you are a strike customer when you sign up to use the primal wallet.
I'm not a fan of this but understand for onboarding  new users 

 This might be some of the issue that I’m having with Primal then. I’m setup through Alby and not Strike. I wonder if that’s why it won’t allow me to setup my wallet. I’ll check this out, thank you for your help! 

 Ah yes I've heard of similar issues with this. No problem! Hope you get it figured out for yourself
