This official announcement is over a year old. I am having this problem now in June 2016. I am using my home desktop computer, not anything wireless.
When you say you created a new profile did you mean a new password? I tried a new password but it has not worked. When I could not stay signed in I checked announcments and saw nothing. I checked forums and saw info from 2015. Now I can see I'm not the only one with this problem. I've been using the Remember Me option because the stay signed in has not worked. Maybe you can let me know what you meant by a new profile. I'm not that great with this sort of thing...Thanks:Chris
The PROFILE is your Windows User Profile.
When I created a new User Profile on my PC I was able to use Internet Explorer to logon to Verizon and check-off the "remember me" option and it keeps the setting for some reason. That is still a mystery, no comment from Verizon.
(I now have to copy the old user files to the new user if you want to use only one profile, haven't done this step yet)
