Problem

When attempting to edit a Confluence Cloud page that contains a large number of Jira macros and a Team Calendar macro within the Legacy Editor, the page fails to load and displays an indefinite spinning icon.

• Additionally, Expand macros do not function as expected in this scenario.
• Issue can also occur during page View, but mainly prevalent in page Edit

Environment

• Confluence Cloud
• Legacy Editor
• Pages containing more than 20 Jira Legacy macros and a Team Calendar macro

Steps to Reproduce

1. Create or open a Confluence page using the Legacy Editor.
2. Add a Table of Contents macro.
3. Insert more than 20 Jira Legacy macros within a table (ac:name="jira").
4. Add a Team Calendars macro (ac:name="calendar").
5. Attempt to edit the page.

Expected Results

• The page should load successfully in edit mode, allowing the user to make changes without any loading issues. All macros, including Expand macros, should function correctly.

Actual Results

• The page does not load properly in edit mode, displaying an indefinite spinning icon, preventing occuring edits. Expand macros don't properly work under these conditions.

Workaround

• For Edit;
  • To workaround the issue, encapsulate the Team Calendars macro within a Panel or Expand macro and save it as a new version of the page.
  • Remember to use a '?NO_SSR=1' value at the end of the page URLs to bypass the loading issue:

    • https://<instance-url>.atlassian.net/wiki/spaces/<space-key>/pages/<page-id>/<page-title-with-loading-issues>?NO_SSR=1
      

    • This adjustment allows the page to be edited successfully multiple times afterwards.
• For View;
  • Navigate to any other page via the page tree on the side, and return to the original page via the Page tree.
    • This bypasses SSR, preventing the issue;
  • Or use the '?NO_SSR=1' value at the end of the page URLs

    • https://<instance-url>.atlassian.net/wiki/spaces/<space-key>/pages/<page-id>/<page-title-with-loading-issues>?NO_SSR=1
      

Notes

• This issue is specific to the Legacy Editor and does not occur with the new editor, consider converting the pages to the new editor.
• Removing Team Calendar macros also resolves the problem.
