Yeah, it was the default that came with the tablet, there’s even a PC mode where you can use the built-in physical keyboard

I already did that, I also tried deleting YouTube entirely (as mentioned by another commenter), but it didn’t change anything. I also get the same error on all other apps, so it probably isn’t an issue with YouTube links specifically.

I don’t think link verification is the issue as it is present on all android devices, including my phone on which links show up just fine. As to your solution, are you mentioning the add button on the popup ? Because it doesn’t seem to do anything

Edit : To be more precise, link verification seems to be what links apps are allowed to open in the first place, so it probably has something to do with it but it’s not really specific enough
