Apologies if this should be posted somewhere else.

I have had this TV for about 7 years and have never had this pop up before. About a month ago, I bought a router that uses OpenWRT. With that, I setup up Adguard and specifically one of the lists that is supposed to block devices from phoning home.

Am I nuts thinking that this pop up is due to the TV not being able to offload what has been recorded? How would I check that?
