Good morning,


I am trying to upload a PDF to TEAMS to share with my students.  They need to see the book on their screen as we are going through the lesson.  I went to the share box with the arrow and tried to upload it.  A message appears saying that it can not be uploaded.  How can I upload and share with my students so they are able to read it from their screen?


Also, I had eight students that signed into teams but I could only see two students.  However, I could not see them at the same time.  It would flip between the two students.  How do I get all students to appear on the screen at the same time?  Thank you for any help you can provide.
