Here is how I got #citrine to work as both a local relay and as an exposed onion service as outbox relay on my phone. Thanks to Ryan (nprofile…g7ce) for the idea!
Download Citrine and start as local relay
Open Orbot Tap more Tap onion hosted services Tap user services Tap +
Add any name to service Add 4869 to both ports
Hit save Exit from orbot Restart orbot by closing out or force close Restart orbot and connect orbot vpn again Tap hosted services and copy new onion url
Open #Amethyst and go to relays Add ws://yournewonionaddress. onion:4869 to outbox relay Remove any other outbox relay Hit save
