Good morning! I have a question. Lately, I've been playing around with Microsoft Teams to familiarize myself with the program. Recently, I went into one of my classes that I created so I could practice sharing my PDF document. I tried over and over to share the doc as though I was teaching my students, but it never worked for me. On the screen, it stated that I could only share PowerPoint files. What could I possibly be doing wrong? Please advise.
