That is because Chamberlain does not permit the HE MyQ app to read the status of the door, but it can open and close it. It's the reason many HE MyQ users use a local sensor on the door.
Having used the local He MyQ app in both with sensor and no sensor modes, and having the door remain partially open overnight with no local sensor mode, with no warning from the MyQ app that I normally receive, I strongly suggest using the HE MyQ app with sensor. I changed over to "with sensor mode" about two weeks ago after pushing a zigbee signal into the concrete walled garage with Tradfri repeaters.
That's correct. It's a one way street from HE to MyQ. No feedback or unsolicited updates, that are not available due to Chamberlain licencing limitations. Hence the use of a local sensor on the door.
Posting on the Myq Lite thread is probably the best place for any additional questions. I'm sure someone has tried with the now payable IFTTT interface.
