Yeah, u have tried all types of relay selections. They all suck. People keep missing things. Worst is that majority of relays go offline / get too busy to reply for a few minutes/hours almost every day. So the fact that the app couldn't connect for hours doesn't mean much. The relay might still comeback at any time. Also, 95% of our relay connections go through Tor by default. So if Tor is slow or if the monitor doesn't check the connection ability in the same conditions of the phone (which change from mobile data to wifi), that is also a problem. But in the end, if the user is still using relays that don't exist anymore, it is likely that they will miss things. They will see less and less data over time. This is regardless of well apps connect to them.
