AT&T related help: Welcome back
I get HBOMax subscription free with unlimited plan. Now that HBOMax is just Max, can I upgrade to the ultimate tier?
The current subscription provided by AT&T is the add-free tier which does not include 4K or dolby atmos. I would like to upgrade to the ultimate tier which does include 4K and dolby atmos. Is this possible? I cannot find a way to do this through account management.
