Hi, I updated Confluence to version 9.2.1 and have now the following message on some pages in Confluence.

How can I find out which app it was and what it was linked to?
When I then installed the Gadgets for Confluence app, it gave me the following error message.

We really need to find out how this works again or how I can get it working again.
Does anyone have the same problem and know a resolution?
Thanks and best regards, Vera
