Unable to edit smartsheet items in Microsoft Teams

Hi all,

I have a client that uses Smartsheet and will be joining our Microsoft tenant shortly. I created a Smartsheet account to familiarize myself with it and connect it to Microsoft Teams. I've created a tab and connected a sheet/report and it's showing me (View only) on Teams unable to edit.

I granted a co-worker Admin rights and myself Owner and still can't do edits on Teams.

Does anyone know what might be wrong?
