@gmbl Have you receieved any info about this? Im experiencing the same issue. The app is stuck on an internal loop. I tried opening inside an icognito window and things only got worse causing CHROME to crash.
Some further information. I tried opening the app using Safari, and received an "ENABLE COOKIES" message. However cookies are enabled in the browser for both shopify and pinterest, i cleared them out and did it again same issue. Ill post anything else i uncover, pinterest support is quite literally the worst on earth, so don't expect them to EVER fix this if its on their end.
I’m having the same issue. I can’t connect Pinterest automatically. I added tags manually, however the tag history in Pinterest says my codes aren’t “healthy”. This is why I rather I connect automatically. The blank screen pops up and never loads. I cleared my cookies and restarted the computer tried again and it loaded to the connect page where I need to login and connect Shopify and Pin but it then stalled again. HELP SHOPIFY!!
