I tried:
- socks proxy
- socks proxy+vpn Mode (for the app only)
- vpn Mode (for the app only)
And in all of them, even though Orbot was not connected, I could read and write nostr event. That's what's I was complaining.
Now misteryously it went back to work as intended: no Tor connection, amethyst stops working.
I Attribute it to a GrapheneOS update
