User impact: Admins may be unable to access the SharePoint Online admin center.

More info: Additionally, the top navigation suite bar (app launcher, search, and settings) doesn’t load across SharePoint Online sites for any users.

When attempting to access the SharePoint Online admin center, admins may see the following error message:

“Sorry, something went wrong.”
Technical details of the error may reference an application initialization error.

Current status: Our analysis of the information gathered from a subset of admins who reported impact is persisting after the deployment of the configuration change indicates that a stale caching issue may be preventing them from receiving the fix. We’ve applied a solution to resolve the caching issue, and we’re reaching out to the subset of affected admins to verify this has fully remediated the issue. This verification will help confirm our understanding of the root cause of the issue.

Scope of impact: Some admins or users attempting to access the SharePoint Online admin center or sites may be impacted.
