Hey BB. There is nothing worse than end-to-end attribution breaking am I rite?

Honestly, my first step is to always reach out to the support team via Chat. They are SUPER helpful and knowledgeable about things and can at least point you in the right direction on a fix.

I’m assuming you already looked at all the settings of the campaign to make sure tracking was included in your links (if not handled at your account level globally).

Sorry thats not a solution, but I it should get you closer to an answer.

I’ve also seen delayed data in the past, so check again tomorrow to rule that out.

I’m going to echo ​@TJ Mapes here, sometimes I’ll give it a few hours or check the next day before I count any data to be finalized.  You can also check Klaviyo status to see if there are any operational issues (You can imagine, their systems are tallying millions/billions? of emails per day).
