1. Blocking only DNS, is not the best option. Use DNS redirect to your choice of DNS. This way equipment with fixed DNS like Chreomecast still works, and you still can control DNS filter.
2. You Video is very cluttered. Get rid of TIFTOK in front of the Video (if needed it, put it down on the side). Do not show recording windows etc.
