Accessing and using Microsoft Teams on smartphones and tablets across platforms
Hello Subramanian E R
At the moment, there hasn't been any official announcement regarding a specific update timeline for Microsoft Teams on iPhone Duo. Based on the latest information available, Teams has not yet been optimized for the new iPhone Duo experience, while some other Microsoft 365 apps such as Word, Excel, PowerPoint, OneNote, and Outlook have already received updates.
As iPhone Duo is still a relatively new device and more users are beginning to adopt it, I think it may take some more time for Microsoft to roll out updates across all Office apps. Hopefully, Microsoft will release further optimizations and updates for Teams in the near future.
In the meantime, you may wish to submit feedback directly through Teams > Settings > Help & feedback > Send feedback so the product team can better understand the demand and hopefully prioritize this update sooner.
If I come across any information regarding a future update, I will keep you informed in this thread.
Kind regards,
