One of our organization members recently came to me because he was unable to log onto Field Maps. I tried signing into AGOL with his username and password on my computer and got the same invalid login message as he did. I then had him use the forgot password option, but he received an email saying that his account had been deactivated. I sent him an invite with a new user name, and now it says that the member's account has been blocked. I already sent an email to accounts@esri.com, but I thought maybe somebody on here would have an idea.
