  • Do you have your own integration, or is it one of our official ones?

  • Check browser console when opening a document for editing:

  1. Open a document and wait until page is loaded;
  2. Open browser console (F12 in most browsers);
  3. Reload page with opened browser console.

Once page is loaded again, check Console and Network tabs for any error entries. If there are any, please make screenshots of them.
