yes, i found a way to make it work by taking off the 2auth verification with "security": {
"staffDeviceVerification": false
} so i could acces the back office and fix it all.
in the mean time i noticed that the Activitypub network is now working well done guys @girish and all the team - i was wondering, if you could explain a bit how it works. Is it an independant activitypub server that is setup per ghost app ? Does it take more storage ?
