Android users may experience app launch failures or delays for native app bundles in the Teams mobile app
Service Degradation

More info: This specifically affects users who recently updated their Teams mobile app to the latest version of 1416/1.0.0.2025193702.
Users can work around this issue by relaunching the app bundles multiple times, as the specific app should successfully launch within a few attempts once the associated app bundles are also upgraded to this latest version of Teams. Users may also be able to avoid this launch failure by signing out and in of the Teams mobile app again, which should clear the associated cache of these app bundles.

Current status: The service providers suspects this issue is due to native app bundles in the Teams mobile not getting upgraded alongside the Teams app itself, which causes incompatible app versions to attempt launch. They're developing a possible fix that addresses when these app bundles are upgraded as part of the Teams mobile app upgrade process, to confirm the root cause and to avoid these outdated app versions from being called prior to fully updating. https://status.dal.ca/service.php?Service=37 2025-10-28 08:43:08 Ticket ID: 21089 (Maintenance - Scheduled - Medium)
