Ok. Clear about coinos custodial and Alby non custodial.
I created an Alby account yesterday
and get a custom name address (with archjourney). I didn't want a subscription.
Usually i am Nostr from mobile.
So after I created my alby account I had to link an nwc wallet there (and I couldn't find an nwc string in the alby dashboard and settings).

If I understood correct there are three Alby things.
Alby Hub
Alby extension and
AlbyGo.

And you must subscribe for an nwc Alby
OR I must link there another nwc.
Right??🙄
