Sometimes I noticed homelink delays for 10 seconds or more and I used to push it again. Now I just wait and it eventually works. Let me know how your fix works.It does very similar, there is another post where the issue was fixed by redoing firmware, see Park Assist Unavailable
So far i've scheduled mobile service for this issue and will let you know how that goes.
The most annoying thing for me is falcon doors which I now have to press 3-4 times to open and homelink triggering 2 times so i can't really open/close the garage.
