Wow, umm... sorry?
This is literally the first time you've acknowledged there being a problem with these systems. So that's good, that's progress!
I would (respectfully) again suggest that perhaps Mostr be shut down until it can be fixed, because (as I've demonstrated upthread) it really presents a sort of deceptive view to less-technical users that 2-way communication is possible just like any other npub, when really this doesn't seem to be the case.
Also, maybe have it hosted somewhere else than Gitlab, which requires paid subscriptions to submit issues?
