Overall, it just purrrrrs along, no real issues, in fact, no issues.
But, lately, on Samsung TV, when I hit Home button, sometimes, seldom, I get Samsung's advert to the left of home icon on screen, either with colour image, or, blank background.
When I've tried to action that, got an image/ icon on screen (that I can't duplicate now, sorry) that won't load anything, times out.
How can I research/troubleshoot such intermittent issue
When I saw it last week, I running multi hour imapsync process, 20gb transfer, so at first I thought I was maxxing out RPI - though, top load average was below .2, but even after imapsync finished, still had that issue
