I’ve noticed that a couple of times from the Ultra, then it seems to straighten itself out. Maybe a wobbly connector? But it only got used once, when I put the card in it. So probably a software update glitch.
Tech is like any other useful complex product, **** wears out. With electronics, they will over a long period of time get enough microscopic wear that they will start to go all poopy and stuff, but generally there isn’t any suspense — they work right out of the box, or they don’t. :^)
I’ve got an Ultra, too. I have it hidden away so I need to get the ladder out tomorrow to reboot it. It’s the first time it’s gone wonky on me. The Roku products have all been very stable and reliable.
