I cleared the cache; it helped me log in with nsec.the app, but only for the first opening; it stopped working again - loading communique only.

If I want to send ecash from cashu wallet it generates a token but iOS npub.cash does not offer an option to enter this code. Instead there is an option to generate the invoice by selecting send button. Thi generates qr code only. I think I am a little too early in its development phase. Will try I. Few days time.
