Yes, if you’re subscribed to Max through YouTube TV, I believe they charge $16.99 per month for it.
Another option is to subscribe directly through Max. The Basic plan with ads costs $9.99 per month.
If you sign up for a standalone subscription and then cancel (I’m not sure how long you need to keep it before canceling), they often offer a special deal to stay. Right now, I’m paying $4.99 per month for 3 months (with ads) through one of those offers.
