TEAMS invites look like emails in Web but not on iPhone

TEAMS invites look like emails in Web but not on iPhone

Hi.  I don't remember this historically, so I think this is a relatively new issue.

Two separate people from separate organizations sent me a calendar invite, presumably from Outlook (since these are TEAMS meetings).  In both cases, on iPhone everything is great, I can respond, and it looks like a calendar invite. 

On the Web version of Mail ... these items have the calendar icon to the left of the sender, but they don't look like invites, I don't have a choice of whether to accept/decline, and the date/time of the meeting does not appear anywhere.

Is this a known problem, and is this just something I need to work around?


Regards,
Brian
