Subtitles keep turning on
Ran into this and it just started to happen. For me what fixed it is when one app has it enabled it enables for all the apps. I found the one app that had it enabled in the app not on the ruku itself (peacock for me) and and finally stayed across the board. Checked all my other roku’s in the house and I looked to have fixed it
So I fixed it. At least on my devices (two of the newer Ultra boxes, the ones that do Dolby Vision). There might be other symptoms on other streamers or the TV, but I'll share what happened and what I did.
I was having the same symptoms as much of what I have read here. The captions were always on upon starting something. If I turned them off in the app itself, they stayed off for the duration of the show I was watching, but only if I continued straight through. When the next episode began, they were on again. Even if I paused to take a leak, they would return upon restart. If I turned them off globally in the menu, it was useless. They would be on in the show and then if I returned to the global settings it was as if I had never made the change.
The one thing that helped me was that this is a fairly recent problem. Up until last month this never happened. What happened last month? Well, for me I got rid of my cable service and wanted to see if any of the live TV apps made sense. So I tried them. Sling, Fubo TV, Philo and YouTube TV. I ended up not using any of them - but I didn't delete them. So yesterday I did. The problem is GONE.
Someone either in this thread or one of the others had mentioned Sling, and that's what made me try this. I don't know which of those apps were the trigger and frankly I don't care. This is Roku's problem. I feel bad for saying that because I'm a video product engineer for a major manufacturer and it's in my nature to get to the root of these things. But I don't have access to the code for Roku, and I'm sure they have people who actually get paid to debug these problems. But if this "fix" can help some of you or one of the Roku coders, then good.
As always, YMMV.
Good luck Roku team...
