I'm trying to log in to my email. I just get the BT logo and 3 little dots which disappears and then I get the log in page which just disappears before I can fill it in
As there has not been a flood of messages on here I would suggest its not a wider issue.
I would perhaps clear your cache and cookies (Browsing history) on the device you are using and failing that use another browser or device to try to rule out issues there.
Failing that I would give technical support a try
I'm getting exactly the same. Down detector showed an outage around 03:00 with some reports around 06:00. I managed to log in to one account, but I'm unable to log out/switch user. Frustrating!
