GitCitadel also has a private group, now, at https://coracle.social/groups/naddr1qvzqqqytlgpzqzp7p4ekweu59qlue8u46gtfjm30w33r527zr6n2hz89ejg4cnyxqqgrywfjx5cnxvfexsursv3hxccny2z3luq/ but I can only seem to login to Coracle using nos2x with Kiwi browser.

Nos2x with chrome and Nos2x with firefox and anything with Amber, all seem to not work. 🤷‍♀️  I can't figure out what I'm doing wrong or why it worked in that one particular case.
