Thanks for confirming. mike (npub1cy4…j9rp) apple is very sensitive about being able to subscribe outside apple pay in all. This is why all in app pay functionality is fiat/apple pay only (and you can only find a sats option on the website).
Are you able to find the manage functionality on the damus purple website? What are you trying to achieve?
