since installing Norton 360 on my Mac I am no longer able to use my Cashrewards. I open a site that is partnered with cashrewards eg: booking.com or agoda.com, I click on the activate tab for the cashrewards and constantly get the error "this site can't be reached" it also shows, check if there is a typo in click.linksynergy.com. then underneath is shows DNS PROBE FINISHED NXDOMAIN with a tab to reload, which doesn't work. This is so frustrating as cashrewards is exactly that. When using certain sites to purchase items that are partnered with cashrewards I get a % or monetary value back to my cashrewards account. So basically norton is now costing me money. Can anyone help me resolve this issue, in the simplest of term as I am not IT trained at all. Any help appreciated.
