Title: Some users may be missing some icons and headers within the Universal Windows Platform (UWP) Microsoft 365 (Office) app
User impact: Users may have been missing some icons and headers within the UWP Microsoft 365 (Office) app.
More info: The impact was specific to users with legacy parts, alternatively known as plug-ins, enabled.
While we were working to remediate this issue, affected users could’ve updated their app version from the Microsoft Store, un-installed and re-installed the app, or accessed the content via the web portal at https://www.microsoft365.com
Final status: After further investigation, we determined reverting the update that contains the code error most efficiently remediates the impact, and after completing this reversion, we’ve validated that the impact is resolved.
Scope of impact: The impact was specific to a subset of users using certain legacy parts in the UWP Microsoft 365 (Office) app.
