@kirby@nukie@ruin Are you sure it showed with @poa.st and not @fba.ryona.agency? Because if not, the bug might lay deeper than that, working only if the proper account doesn't exist in their DB (because the domain is blocked). Though that might be an ackoma quirk which I shouldn't be concerned about; tests with pleroma proper showed that it just doesn't work on 2.4 and lower.
@nukie@kirby@ruin I've cherrypicked Alex's fix before the proper MR got merged. Don't see how it can affect notifications, but won't be suprised it somehow does.
