Banking Protection Feature Failing with PayPal

Hi.... I'm using Windows 10 and Google Chrome. Activated Norton "Banking Protection" for the first  time to try it. Tried to make a transaction through Pay Pay on Ebay. The transaction would not go through.  The  screen would just flash and return to the Pay Pal screen asking me to "Pay Now".   Disabled the Banking protection feature and the transaction then went through fine.

Tried again (re-activated "Banking Protection") to use PayPal on a supermarket transaction. This time it took me through to “Isolation Mode” (which I didn't get before) but when I tried to "Pay Now" it crashed me out of Pay Pal and my supermarket login. So disabled  “Banking Protection” and tried again and transaction went through fine.

"Support" suggested changing my browser (which I don't want to do unless I really have to)... Wanted to find out first if anyone else has similar issues with the "Banking Protection" feature to try and identify where the problem is....or if it was not meant to be used with Pay Pal?
