Unable to login to HBOMAX using browser or HBO app on MAC but can login to HBO app on Iphone.
As of 8/21, I was logged out of HBOMAX on my Mac's browser and HBO app. I've cleared cookies and cache and tried firefox, safari, chrome and brave. When I go to hbomax and choose provider > ATT > sign in > the browser tab says "signing out" > I'm redirected to ATT login page > I login > the screen then goes white and the brower tab says "POST Data". This happens using a browser or the HBO app on Mac... exact same sequence / prompts / messages
I'm grandfathered on the Unlimited Elite plan and it looks like others are having similar experiences. Calling 800 number ended with ATT pushing me to HBO after a few different operators and eventually HBO realized it's an ATT interface thing since I CAN login to HBO IOS app on my iphone without issue....
Any help appreciated as calling in was waste of many hours of time and frustrating. Thanks!
