primal settings indicates the ability to use an external wallet via NWC
Discussion
It looks like that might only be an option on Android. I don’t see that in the iOS version of Primal..
I think WoS doesn't have a NWC option. So it's a wallet side thing not a primal side thing.
Yeah WoS doesn’t support NWC. There is a list of wallets that do support it here https://nwc.dev
