This is awesome; much needed. 

I STILL cannot login with any form of extension via mobile on android (grapheneOS) except for Nostrudel via Amber, using nsec bunker. 

Here's a video of trying to get it to work with npub.pro as shown in your example.

Below the only remote signing that works is with nostrudel, hivetalk and satshoot do not work. 

What am I doing wrong? All my permissions are open and allowed on Amber. 

If this can't be fixed by user, I'll make a significant bounty to get this fixed ASAP.
