I've experienced something like a 90% drop in traffic from Pinterest since we replatformed our website.
We run ads and there's a massive discrepancy between the number of clicks ads is showing too (I know not all clicks will make it to the website, but we're talking GA shows about 2 a day, where Pinterest analytics has outbound clicks at about 40/day.
Tag manager code seems to be installed fine and I am searching for 'pinterest' in referrals in GA rather than source.

Thanks for your help, this is driving me a bit mad!
