It’s looking quite bad. Signal started locking and basically immediately removing accounts which don’t have the last resort PQ key set. I thought we had it set correctly, and from what I can see in our sources, we have it set correctly.
The “good” news would be, that if my guess is right, the most recent accounts should not be impacted. Another good news is that Signal has the APIs to actually check the consistency of the prekeys, but we never implemented that.
