You are correct @helene7t7, the changes were backed out shortly after being implemented. I guess we should have all been more ready for this change.
To be honest, I'v e wanted to get away from he MyQ being the only implementation I have since it is not 100% local. I do like having the wifi gateway as a backup is Hubitat is down but having total local control means I won't have a problem if my internet is down.
Also, if you're looking for a REALLY cheap alternative opener device, you can use any smartplug, an old 9v-12v wall-wart style power cord (how many of those do we all have laying around!) and simple $5 automotive relay. Simply set up Hubutit to turn the smartplug on for a second or two, wire the end of the wall-wart's plugs into the coil side of the relay and then the switch sides of the relay in parallel to your wall-button. Works like a charm and if you find stuff on sale you could do it for around $15-$20.
That said, I did try the update to the SmartThings app and it does work again. The nice part is that since it's a cloud integration, I didn't even have to power up my hub to use it. Just installed the updated app and drivers in the IDE and added the smartapp from the phone app.
