Nice, but I would be happy if at least one of these would work a bit. 

* lnw.cash: Blank screen on Android, can't receive anything on desktop. Receive button does nothing
* nuts.cash: No Amber login on Android, crashes browser on desktop
* nutsack.me: no NIP-07 login at all
* highlighter.com: No login on Andreoid possible. New wallet button on desktop does not work. 

Any hints? Browser is Firefox on desktop. 

 When was the last time you tried nuts.cash?

It should be more stable on the latest release
