When we try to activate our HBO Max account we are able to log in on the AT&T watch tv ( the text verification said that we already have an account) only for it to immediately sign us out. Any work arounds or ideas what is going on? Also when selecting provider on HBO Max log in there is no plain AT&T (just u-verse and AT&T TV). When we log in with AT&T TV is says that it does not recognize us. We do not have u-verse.
