I was able to read through the logs last night and again today. There were a couple of odd things in there and I've generated some tickets to follow up on them. I don't have an explanation for the issue yet. In your 0.7 log the printer reports an error saying that it was unable to heat to the target...but i saw another attempt to heat later that worked.
Another set of logs could help rule out (or in) a few things. For example, I saw a FW update, and some errors trying to connect just after that. After ~30s the software is able to connect. Another odd thing is that you were able to start a manual heating job during that 30s period. Not sure how because the start button should have been disabled. If you do this again can keep an eye on the connected/disconnected status in the upper right, knowing what that says would be useful.
ALL: Some logs from others could help. They will help narrow done the common steps needed...or reveal that there's more than one bug here.
