Hmmm Strange! Do you see your npub in the lightning address section?
Discussion
Yes I do and it follows with the “@npub.cash”
that's odd. how do I reproduce this I wonder. which device are you using? Can you try on a different device? (Don't restore your seed there, try a new wallet)
I reproduced it again with a new wallet on desktop as well using Apple M1 MacBook Air. Earlier was with an iPhone. Tried two different nsec & same behavior occurred.
If you need more specifics about my set up, let me know where I can contact you.
