A few questions:
Are you logged into the same Amazon account when you watch Prime? Are you aware that earlier this year, Amazon added commercials to the "base tier" of Prime video and require you to "Go Ad Free" if you don't want them?
If you're logged into the same account and you've gone ad free at Amazon, then there should be no commercials on Prime.
(I can't say anything about Max since I don't have that.)
Banned but back. Because why not?
