It’s beyond frustrating and if they know it’s a problem, I don’t get why they aren’t on top of it to fix it. Ugh. Im glad at least if I want to, I can make reservations using my fiancés account but it’d be nice to use my own.
And I did the same as you with trying all of the different and private browsers, different devices, app, website, laptop, and also deleted credit and debit card info and re-added. It’s strange how some of us have problems and some don’t. Like I’m curious as to what makes certain accounts have the glitch and others don’t.
