I have the same problem, I think. Also on Bones, LOL, but on other shows, too.
It seems to me the pattern is that the screen freezes while showing a Roku splash screen - usually at the start of an ad - and then after I give up, escape, and resume (same as OP), a Roku add plays. As if it's a transition glitch in the Roku ads.
After re-reading the original post, I want to say it seems more recent than last January. More like just in the last 2 or 3 months I realized I have to keep jumpstarting the show again. (And if it _is_ a media glitch, it's arrival is not necessarily aligned with a software upgrade.)
It seems like the screen is locked waiting for something to complete (SKIP, OK, etc.,) or maybe a timer that didn't get started. Since there is no way to kick it, you have to exit and resume.
Hi @Chrysippus,
A warm welcome to the Roku Community!
We're sorry to hear about your experience with the ads on your Roku device. We have users who reported restarting a Roku device along with the router helps them resolve the issue. Could you try this on your end? We recommend doing this from the Settings menu by navigating to Settings > System > Power > System restart. (If you do not see a Power submenu, skip to the next step).
Please let us know how it works.
All the best,
Chel
