Official AT&T website and Android phone application SO SLOW!!!
I have been a loyal customer of ATTs for many years. I have had both positive and negative experiences in that time, but generally they have been good. What has been consistently terrible is the website and phone application. Also, every ATT application for android (My ATT, Call Protect, etc) are also this way, glitchy, buggy and slow... very slow.
Just the simple act of trying to make payment can take minutes and minutes of waiting for the page to load. Forget about using the website for anything else, it's atrocious.
Software / website does not appear to be ATTs strong suit, but at the very least paying the bill should be seamless.
