Issue Status: ONGOING

Issue Description: Users may not receive the join option in Teams iOS for meetings or calls active on another device.

Current Update: 02/07/2026 08:53:00 AM– Microsoft is continuing to apply the aforementioned configuration and as this deployment process progresses across the affected environments, users should start seeing mitigation. They will anticipate this deployment process will be completed by their next scheduled communications update.

Scope of impact: Impact may occur for users joining Teams meetings or calls from the Microsoft Teams iOS app on a secondary device. This section may be updated as our investigation continues.

Root cause: A latent code issue introduced a dependency on an authentication configuration, preventing the companion join banner from functioning as expected.
