Pinterest shadowban

Hi everyone! I'm new to posting here, so please go easy on me. I've had a Pinterest Business account since 2020 to drive traffic to my blog, and it has been working well for the most part (about 70% of my traffic comes from Pinterest, even though I’ve not been the most consistent!) Most of my content is original (photos I take myself or stuff I design on Canva. I promise no AI images here!)

Everything was fine until April 20, when my traffic completely tanked. I'm talking from 20k impressions a day to under 1k almost overnight. I contacted Pinterest, and they said my account is totally fine. No glitches, no shadowban. I’m seriously stumped and don't know what to do!

Has this happened to anyone else? Any idea what could be going on or how to bounce back?
