Yes, the app is very poor. The settings seem to get lost sometimes, but it was even worse before the last update. It rarely gets any updates.
Occasionally the app tells me no car is connected, but the charge point works just fine.
Personally, I don't bother with the app. Setting the scheduled charge times using the car works very well for me and I use the Tesla app to set charge level, so I just set it low when I don't want a charge. The fewer apps the better.
Likewise, the actual charge point (EO Mini Pro 2) itself is rock solid and I have never had any issues between that and the car. To me, this is all that matters.
I have written to their support, but they just become defensive and don't seem to want feedback. Inside the charge point itself is a Raspberry Pi that controls it, so it's more than capable should they wanna make the most of that.
