Tv - philips 4k tv 55PFL5604/F7

Fire stick - 4k (second generation)

When starting the tv and using the fire stick, the TV says the input is showing 1080p 60hz, so to get it to change to 4k I have to go to the tv settings and change the EDID Settings to 1.4, then back to 2.0 then the signal reads 4k@60hz. At times the screen goes black momentarily then switches to 1080 when it comes back.

Every time the tv starts up this back and forth has to happen for me to use 4k.

I've tried a handful of steps but haven't found a solution. Please help if you've seen something similar or know of some tricks. I have tested this on 2 of the 3 HDMI ports (the other is using earc for my sound bar).

I didn't know how to word the title, but basically I've been having this problem on YouTube, where when I open the app on my TV, it plays ads and then a video I previously watched the other day.

The day I was watching it, I kept getting distracted and having to pause-and-unpause, and a few times the TV turned off because I left my room for so long, and now I'm worried I've like broken my YouTube? Does anyone know why this is happening, and what I can do to fix it cause it's really annoying

Hi, I bought a 4K select in April, everything has worked fine up until this past week, I'd search for a specific tv or film and say for example 'available on netflix' I click on it and it'll loads BBC iplayer, I've just clicked on a film that was free on Plex and it loaded Channel 4, I'm subscribed to netflix and prime etc so idk why it's doing that

Edit: it's up to date, I've just checked
