Just lately I have to log in to Paypal for every purchase even when I logged in minutes ago, I also tick stay logged in box every time but it seems to ignore that. Any idea what's changed or what setting I have to select in ebay and/or paypal? Something has changed somewhere, thanks
Are you using a browser in private mode or have you turned off cookies or are you deleting them every time you exit the browser?
If you are doing everything as you always have, it is probably a browser issue. I would clear the cache, close out of the browser, restart the machine and then the first time you buy something, click the remember me box and see if that works.
This might be related - when I was buying two products from the same seller last week, it tried to make me log in to PayPal twice and pay for each item individually. This was because I selected "Buy it now" instead of "Add to basket" - so it was trying to make me pay twice rather than add my items together and pay once (which it used to do for the same seller). This is different to how ebay has always worked for me in the past.
