I'm having the same issue, as well.
When I go to Shopify>Apps>Printful>Sign-In Page,
I try to connect my shop under the checklist (Connect Your Store), on my dashboard.
Then I go to Connect Store (Choose Method)>Shopify>Add App
Then it opens the Printful sign-in page and I am back at square one.
I've tried re-downloading the app, but it takes me back to the Printful sign-in page again.
And I end up at the dashboard checklist again.
Here are more screenshots of the steps I took to get here.
Hope this helps. Thank you for your time!

Solved my own problem, posting in case anyone else is doing what I did (duh!!). Everytime I got to the Printful connect screen, I was hitting "sign up with email" and getting nowhere.
I realized I should be clicking on the sign in link for existing accounts, since I had already set up my Printful account prior. Voila! Worked when I realized what I was doing. Newbie error
