Multi-device Meeting and Synchronization Issues

Using one link should normally place everyone in the same meeting, but these symptoms can occur if somebody opens another occurrence, a copied invite, or joins with a different account, tenant, or anonymous identity. On every device, open Meeting info and compare the Meeting ID, not only the visible link. On the iPhone pre-join screen, confirm the organizer account and join from the calendar event. When moving between devices, use Transfer to this device; use Add this device only when both should remain connected under the same account. The Teams administrator should then locate the event using UTC time and organizer in Teams admin center, compare conference and participant details, and collect client logs. Different identities can also explain missing chat history. If Meeting IDs match but sessions still split, open Microsoft support with those diagnostics. Report the iOS feedback failure separately through desktop or Microsoft 365 admin support.
