How can I use #Amber to login to nostr sites that use nip-07? For example, nutsack.me ?

#asknostr  

 You can't.
To use nip-07 on android use the Kiwi browser and the nos2x extension 

 That's what I've been doing, was just hoping Amber could provide a more seamless way... 

 Unfortunately, no 😔 

 We could be optimistic and say not yet
