Netflix shows buffering on MacBook via Safari

I have not been able to watch anything on Netflix for the past few days, it just buffers. I don't know if it has been since last software update (Catalina). What is weird, is that I can watch shows on my iPhone - no problem.

I am able to watch shows on Hulu, Amazon, etc...my internet connection is great.

I saw a message about making sure to disable content blockers, and have allowed pop up windows.

Welcome any advice.
