I can get into and move through my streaming apps (Hulu, Netflix, Disney+) but when I click on a show to watch it just buffers for a minute and then gives an error message. The only resolution I've found so far is by unplugging the Roku and plugging back in.
This doesn't fix the problem, but you may find this an easier method for restarting:
Settings > System > System restart
I am having the exact same issue. Have you found a resolution yet?
Nope...and it has gotten worse.
