Currently we have the functionality to select taggable terms in a managed metadata field from a combo-box in PowerApps. What we do not have have is the ability to browse through the hierarchy and select the exact term that we need. Searching is fine, but it becomes confusing when there poly-hierarchical terms. In the current implementation poly hierarchical terms show up multiple times in the combo box and is difficult for users to select the right term in the hierarchy. Allow the tree view as is implement in the SharePoint will remove this confusion and ensure users select the right terms.
