Blocking error (pro version too) and help desk NOT WORKING

First one: problem with contacting you:

I bought the pro version but none of your websites’ ticketing version works. when I tap submit my console is full of errors, no message has been sent!

Second: In the last days an error appeared and is preventing to show my instagram social wall from a website. The error is:

(#100) Object does not exist, cannot be loaded due to missing permission or reviewable feature, or does not support this operation. This endpoint requires the ‘pages_read_engagement’ permission or the ‘Page Public Content Access’ feature or the ‘Page Public Metadata Access’ feature. Refer to https://developers.facebook.com/docs/apps/review/login-permissions#manage-pages, https://developers.facebook.com/docs/apps/review/feature#reference-PAGES_ACCESS and https://developers.facebook.com/docs/apps/review/feature#page-public-metadata-access for details.

What can I do? I found out I’m not the only one! Already tried to re-auth and other things. Thank you!
