Here is what I did for Flashing lights.
I just tested my door. If I open it and stop it.
I get an error with MyQ app. Door has been stopped
If I hit the button again it closes.
If I don't let it close and hit the button again than it will only open to original starting point (stopped the first time). Get another error with MyQ app that the door has stopped.
I don't see what you are seeing or I'm not expecting what you are expecting.
To be honest other than beeping and flashing lights it works just as good or better than the MyQ integration.
I'm sorry I couldn't be much more help.
