After migration, the Handy Macros page in the Apps section fails to load.
This issue can be caused by the fact that the app doesn't have enough permissions to perform the user permission check.
The root cause of this issue is that the atlassian-addons group, to which the Handy Macros for Confluence app is a member, doesn't have product access to Confluence. Thus, even though the Handy Macros for Confluence app has the required permissions, it couldn't get to Confluence.
That said, the Atlassian Support Team needs to be contacted to add the atlassian-addons group with product access to the affected Confluence Cloud site.
After that, the Handy Macros for Confluence app will operate as expected.
This issue can occur when you are trying to install or reinstall an app from the Atlassian Marketplace. In the UI, you will get the message saying, 'We ran into a little trouble. It might just be a hiccup'.

On Cloud, all the sets will appear in one storage without division into categories. For your better navigation among them, set names will get some prompts regarding their origin. Global sets will retain their names, space sets will get the name format "SET_NAME space(SPACE_KEY)", and personal "SET_NAME personal (ATLASSIAN_USER_ACCOUNT_ID)".
