I see you removed eXch from the monitoring even earlier; at least I don't get them in the results anymore. (They are still not found in this mobile ticker, while the link is to a non-functional exch.net domain.) Ok, that's understandable considering the current situation with this exchange.
However, we may not follow others enough, so we don't know much about their status. I would suggest that you have a page, for example, where you will enter a log with all the changes you make to the service. It might be informative for users
Yeah, we opted to remove them early to avoid any issues with stuck coins as they go offline.
Good idea with the status page, we already de facto use our SimpleX group chat for that purpose, because it's the only way we have to put out messages into the world when away from keyboard.
