What is this strange symbol when I try to play YouTube videos on Kindle's Silk Browser?
I had the same problem a couple of days ago. I performed a factory reset and restored my files from the backup and that seems to have cleared the problem, mostly.
I used one of the YouTube apps on the Kindle Appstore for watching videos. I initially encountered the problem while watching a video and switching to another. The emergence of the problem seemed to be unrelated to anything I was doing since I didn't change any settings between videos. I switched to the Silk Browser and encountered the same problem.
Clearing the cache in both the app and the browser did nothing to solve the issue. After the factory reset, YouTube started working properly in the Silk Browser but seems to be encountering the problem again in the app.
In my searching for a solution, I did come across a post that mentioned the symbol and explained that it was a problem caused by a change that YouTube made on their end. The solution offered was to &quot;wait it out.&quot; Unfortunately, I don't have the link to the page since my search history was deleted when I performed the factory reset and I can't remember what search terms I used to find the page.
