Tippy I just went to Goggle Ebay sign in and I can switch accounts it won't let you log out but if you go back to sign in you can change to another account.Bit of a pain but at least I could access my other acc.

ebay is full of **bleep**, 2 days now unable to Logg off they stated Techicians working on it and will be fixed soon, 2 days later account is logged on permanently, more chances of getting hacked,  stupid ebay

It's more than 2 days. And it's weeks - well maybe close to month -  for the problem where you repeatedly have to keep signing in. 

The problem has disappeared. Looks like eBay has done something to fix it.
