Sysyem limits for Confluence: reference?

Is there a page where we can look up system limits for Confluence Cloud?
For example we are interested on limits for https://developer.atlassian.com/cloud/confluence/rest/v1/api-group-user-properties/#api-wiki-rest-api-user-userid-property-key-post , where it is stated:

the number of properties which could be created per app in a tenant for each user might be restricted by fixed system limits.

Hey @marc,

Have you found the answer to this yet? We are also looking into consolidating the number of user properties we have and would like to understand what it means by system limit. The documentation is not clear enough on this part, I would appreciate if you could share some findings on this!

Leon,
Best regards.

Hi @Leon ,
No, I don’t know the answer yet.
