The following will not display on our User's IOS devices upgraded to the latest 4.24 version of Outlook for IOS - 4.2412.0. The documentation here says that it supported on version 4.34 (Which does not exist) https://learn.microsoft.com/en-us/outlook/actionable-messages/ . We have significant amount of time invested in leveraging these tools. Please help me understand what would cause this not to work on the software across IOS devices?
