I‘m also currently using 1Blocker. What makes you dissatisfied with it?

I haven‘t gone that route, I disabled it at router level. Might look into disabling it on VLAN basis and moving the Apple TV into a specific one with IPv6 disabled.

Thanks for sharing! Disabling IPv6 fixed my buffering problems on Apple TV, wired with Premium. I suspected my pi-hole initialy. Its insane that Google is apparently incapable to properly network their services… even if you pay for them.

Sounds like your IT has not configured things correctly and they are most likely understaffed. The move to cloud to save on IT expense is the biggest lie providers tell. If you want the products to work well and fit into workflows they need to be configured.
