Hi, we have created a Yammer tab in Teams, but there are two issues:
1) People cannot edit their comments as there is no functionality to do so (they need to go to Yammer or to do it from the Yammer app at the right-hand-side bar of Teams)
2) URL Thumbnails do not appear when you posted from Yammer in Teams tab.
In addition; I find that Yammer app in the right-hand-side bar of Teams do not pin permanently to the bar (when you pin it may disappear so we need to look back for it in Apps)
Has Yammer App for Teams been designed this way or are we doing something wrong?
