This has been a problem for me for quite a while (definitely over a year), but it's minor in that I just use "Update Now." With 7.12, though, I decided to give it a few days to see if anything happened. I'm still on 7.11 SR2. I believe it's been over a week since 7.12 was released. My PC has been on with Logos running that entire time. It hasn't automatically updated.
Here are my settings:

There are no recent entries in my log files, and unfortunately I'm not in a situation to enable logs and wait for another overnight to see if they have anything useful.
But I did want to report this issue.
Thanks,
Donnie
