Hi felixa86813896 yes, the Internal URL Filters was more of a 'belt &
braces' idea. I think it only affects the Referrers reports, but I
suspect the Marketing Channels processing rules might also use the same
information. It would certainly be a good idea to add your domain(s) to
the Internal URL Filters anyway - it would do no harm, and it might fix
the Marketing Channels issue. - Let us know if it helps.
