The wallets are unique to the specific apps on the specific devices. Meaning if you get a wallet setup on Primal's website, it will not follow you to the mobile app. Every place you have the app loaded, you need to connect the wallet. BUT- Primal on iOS doesn't use NWC or Alby. So you have a few options:

Option 1) use the PWA version of Primal on your phone and set it up that way. I've not tried this, but I know Alby works with the desktop version of Primal and assume it'll work this way, too.

Option 2) Use a different app, such as #Damus or #Yakihonne or one of the other one's I messaged you about.

Option 3) Use a PWA of other clients if you don't like any of the apps. I like Iris and Nostrudel's PWA on mobile. A PWA is basically loading the mobile version of those clients in Safari, hitting the share button, and adding it to your home screen.
