When I log into my Taboola account I end up on the Taboola Ads dashboard... I have a network account. I try to create a campaign and I receive this error message: (3)Error!Currently you do not have permission to access this account (), or it does not exist. I reached out to Taboola support and received this reply: "We would like to inform you that in order to run campaigns with us, you need to create an advertiser account. Currently, you have a publisher account." OK, I get that. But how do you sign up for an advertiser account?
