Running OctoPi 0.16.0 \ OctoPrint 1.3.12 on a Raspberry Pi3+, all upgraded within the last week, using the backup\clean install\restore method.
All works as expected, apart from the system forgetting that Pip was installed & so I couldn't manage the plugins (a re-install fixed it), but I'm having an issue where the browser (Microsoft Edge\Firefox) window freezes after 15\20 minutes, when viewing the Control tab with Pi Camera insert. I use this for remote visual monitoring, so its a pain....
Using F5\ Cntrl F5 does nothing, including trying to select other tabs etc., but if I enter "http://" to the front of the link, then all works as expected, for 15\20 minutes.
I don't think it's browser related, as the same thing happens on multiple platforms\browsers etc.
FYI, one other annoying thing, that I've noticed on my system, is that on re-starting the Pi\Octoprint the webcam Timelapse is always re-enabled, even if I've turned it off, to ensure I don't run out of space on long print runs....
