Anyone seen "errors" in the pixel reporting on converting ads? Working with a client, they have 0 marketing besides us and there is literally like 3% chance someoen would be something without buying through ads. Even so, when our ads are saying 200 sales, analytics is saying 400, but client have over 800 sales. Anyone noticed problems with tracking and have a solution? Like, could it have anything to do with GDPR/cookie settings or something like that? people not ticking the box but still buying?
