 Shouldn't be able to post relay group stuff into a Kind 01 client. Would sort of defeat the point. 

 It was a link TO the group.  

 It was a nostr: link, but it needs to be a hyperlink. 

 That's still kind of annoying.

Let's see...  

 Link works, but couldn't login. 

 Thank you.  

 I really wonder if this is a signer issue.  

 Works, now.
