Mine is working now, thanks Rogers!!!
Which version of the YouTube app are you running? I'm running version web_20200628_00_RC00 on an Xi6-T set-top box. When playing a video, pressing the "Back" button still does not allow me to navigate back one level. I should be able to press this button repeatedly and eventually navigate back to either the Home screen or the top-level search results.
UPDATE: I'm super confused I have 4 ignite tv boxes in my house. I have one box with the 20200624 version which the back button now works perfectly. The other 3 boxes have the 20200630 version in which the back button does not work. Not sure how I have different update versions on each box....please fix this Rogers.
There are two versions of the Ignite set-top box out there: the Xi6-A (made by Arris, with a white label on the bottom) and the Xi6-T (made by Technicolor, with a black label)
Which model(s) do you have and which one works (and does not work) for you?
I am seeing this problem with the Xi6-T. I do not have any Xi6-A's anymore to test with.
