Streaming services not working

I’ve been having this problem for weeks. Most of the streaming services on my iPhone 14 Pro just won’t play anything. Paramount+, Hulu, Netflix, YouTube, … I keep getting an error message.

I’ve updated the apps. I’ve tried both over WiFi and 5G cellular. I’ve tried while my phone is plugged in to power. I’ve tried on different networks. The apps load. I can see all the videos, but when I try to play them I either get an error message or on paramount and Hulu it sometimes plays a few seconds then the screen goes black.

I’m in the USA. No VPN. No adblockers. I don’t have any WiFi or battery restrictions turned on. This is so frustrating.
