Hi, I have been successfully embedding Padlets in Canvas pages for my students to use for the past 5 years. After have just re-made Padlet form last year, with the same settings and embedded it in Canvas it shows up with the error message:

"This padlet is not publicly viewable

Please open the embedded padlet in a new tab to access it. Change the privacy setting to 'secret', 'public' or 'org-wide' if you would like the padlet to be viewable here."

This is despite the Padlet settings already being set to 'org-wide' and made within my university's approved Padlet Domain. 

Any ideas why it's started doing that this year and what I need to do to fix it?
