See my previous response. Clear your browser cache and especially the cookies. You can usually clear them on a per website basis if you don't want to nuke the lot.On my Samsung Note 8, using Adblock Browser, I have to log on every time, even though I have the "stay logged on" checkbox checked.
This worked before the upgrade to the site. Other than that, I really like the new look and functionality of the new site.
I'll have to check to see if this is working using other browsers on my phone, and if it works when surfing on a PC.
