Last evening, I received email informed me I'm a verified merchant. I checked my profile and saw a blue checkmark, but I didn't see price next to titles. I thought it may take time to display. 24 hours passed, all my product titles still no price. I have tagged products to much pictures. I don't know why the price not show up.
I have a similar problem, no prices. There is so little support from Pinterest in this area. I asked my SEO company to research. This is so important to be able to sell on Pinterest.
