That's because of the form that was coming up, my clients filled them up, and then their websites were unclaimed. Plus, we lost all the analytics.
That makes sense. I saw that form pop up on my account too. Thought it was odd, but I filled it out anyway. Yeah, it was a bummer losing all that data!
When the form got filled out, it unclaimed the website. So it wiped out all history of the analytics to the site up until we reclaimed it again. 😭
We are seeing this too on multiple clients' accounts. I did not put two and two together, to realize that it was after the pop-up that appeared last week, but the timing does align. No confirmation on any of this from Pinterest yet?
