Microsoft Team - Default Folder/File Sort

not sure if this is relevant to your situation, but I was trying to add a 'tab' on a channel in Teams that would point to a sharepoint document library. When I added it as a 'document library' it would sort in order of last modified (annoying) and wouldn't even show the 'view' options, BUT when I added it as just a sharepoint site, it opens and sorts in order of name, shows the 'view' options as normal and honors the 'all documents' default settings. Both were pointed to the same location/content, but 2 very different views/looks/functions depending on if you choose 'Sharepoint' or 'Document Library'. Maybe this is relevant to how your are accessing the your document library within Teams.
