Privacy warning, this network is blocking encrypted DNS traffic - Netflix not working

Hi Guys,

I updated my MacOS to Big Sur 11.3.1 on my MacBook Pro and iOS to 14.5.1 on my iPhone Xr and I am getting a Privacy Warning that my wireless provider is blocking encrypted DNS traffic.

Some sites that aren't working at all on my phone and on my MacBook

• Netflix
• Prime Video
• Hotstar

And sporadic issues with the below on my phone and my MacBook

• Gmail and Google Business Suite
• Slack
• Zoom
• Amazon
• Goodreads

What can I do to fix this issue?
