I am uploading numerous files to Teams from Dropbox via File Explorer. Many of the files are jpg's. I monitor the upload of the files to find that some jpg files upload just fine while others will not upload, although they are the same file format. I even try to individually select the files that do not upload and drag them over, but Teams will not allow them to upload.
I have searched for this issue online and everything I am seeing is concerned about uploading profile pictures on Teams, this is not that situation. I am trying to upload files to the files tab within a channel.
