I want to sort of wrap up this issue.
By Design
Currently, when the PIP button is focused, the timeline stays up until it's not focused anymore. This is to prevent the bad experience of the timeline disappearing right before you're about to click the button.
- This has fall out of course in that if it's focused, the timeline doesn't go away.
- This is made worse if you accidentally focus it and don't even know it.
Changes on our end with this
Nothing.
Changes to tvOS or Problems with the Siri Remote
It's possible something changed with the remote to be more sensitive. I would be willing to bet that everyone having this issue is using the original touch based Apple TV remote.
This remote has the absolute horrible side effects of the fact that the seek button is also the same button that allows you to move focus around the interface. Clicking the left and right side of the remote makes it INSANELY easy to accidentally move focus.
What we can do
There's not much we can do here to help prevent the focusing issues. This is just a badly designed remote. Every time you press to seek forward, you have the chance to shift focus. This is why I personally never used that remote, it feels awful. The updated Apple TV remote has a much better experience.
What we CAN do is stop the timeline from being sticky when the PIP button is focused. So we'll adjust it to be a longer timeout before it disappear, so it WILL eventually always disappear...and hopefully before you're about to select it.
