Doesn't make sense have to register first to use a different wallet. Please test the things to see how it works.
Ok this is the confusing part. If you sign in Primal and try to zap, you get that Primal Wallet screen and making you Activate your Primal Wallet. If you go to Settings and then Wallet, I see what you were saying. You have to Uncheck Use Primal Wallet before you can use anything else
