Campaign sequence email not sending

I’m using a WordPress thrive opt-in box for a landing page I’m going to in Infusionsoft form and campaign. And the first email that supposed to be sent immediately is not getting triggered. It just sits. The person is getting tagged in the sequence is getting loaded up into their account and then it takes like a day for that first email to send. What do I do to fix it?

There has, for a few days now, been a known issue around emails taking a long time to send as well as goals taking a long time to trigger. I’m pretty sure they can be tracked on the knownissues page:
