Very disappointed that I have now been waiting for over 50 minutes for your requested DM chat agent. After verifying my email thru the link you provided and receiving your "Authentication successful!" message, he asked me for my email address again , " Just to make sure that I am working with the correct one." That was provided immediately and now, 20 minutes later, no response. Please contact me by phone with your resolution. 

Has anyone else been treated this way?

@MaryAnnAnderson I also had a long wait with the ATT Chat Agent after verifying, then was asked for my ATT internet account number, etc., but at least the agent said he/she would be in a meeting for a couple of hours.  The next day, I was asked to send screenshots to the engineers at an email address, which I did last Friday, 6/10 and still no response.

Same issue here over the past several days when trying to login from my MacBook Air. I am on MacOS Monterey v12.4, Safari, version 15.5. The error message I keep getting upon trying to log in is:

@NewName Thank you for your response. They should have everything they need to fix this issue that started at the beginning of June 2022 and they know it is not caused by the customer. We are all having the same issue and some of the agents above state that their engineering team is still working on a solution. Honesty would go a long way instead of further frustration and time wasted.

HAs anyone had this issue resolved?  I have been logger out 8 times today, this is getting old fast!

@DeadEye57 I'm on the 15th day of the time out issue with no resolution yet.  It has been 10 days since I had a Direct Message chat with ATTHelp who had me send an email to the engineers with screenshots, then they closed the chat session and I have not heard back from anyone ATT with what actions are being taken other than the generic messages on other posts that their engineers are working on it.  

@DeadEye57 No resolution or response here. Just crickets. Very frustrating.

I called AT&T tech support 844-601-4909 on Saturday. They had me do another password reset. That fixed it for the day. Didn’t check login yesterday, but upon trying to login today, same issue again. 
Thankfully, I am still able to access my email from my phone. So I guess I’ll have to live with that until they figure it out. Sorry for those folks who are unable to access their email from any device. 
AT&T should at least post a message banner on their currently.att.yahoo.com page letting people know they are aware of the problem and working on it.  

I have been having the same issues it's ridiculous. I am ready to move to gmail but have sooo much on my att account. I have to keep entering my password and reset it all the time. 

I just entered my same issue and now dont see it. ugh. I am constantly have to reset my password it' s annoying
