Reaching platform limits
Currently, Atlassian enforces tight https://developer.atlassian.com/platform/forge/platform-quotas-and-limits/ to the Storage API. This makes it sometimes likely for Custom Content to exceed these quotas if you have a lot of users accessing the dashboard at the same time. Unfortunately, we do not have a workaround or a way to fix this. If you encounter this problem, please contact us using our Service Desk and please reach out to Atlassian so they provide a more suitable solution to this issue.
