User Bob shared the following comment and I wanted to highlight it on the main page:
Sadly, I just received an email saying that the 5.797 has been removed from the automatic update because of bugs … but that 5.804 is on it’s way and should be less buggy.
I don’t have any other information as this juncture, and I’m still separated from my unit, but I’ll share any more information as it emerges.
