Pinterest pins

Hello,

I have a board named “My IMDbs” in my Pinterest account. I have been pinning my IMDb picks to that board by sharing it. This function does not work more than 2 months and got an error in the attached image. I am able to pin another things from another apps. There should be a problem on IMDb app.

To resolve this I updated my iOS, deleted and re-installed IMDb app, restarted my phone etc. but none of them was use.

Could you please check and correct this issue?

Thank you in advance,

Best regards.
