Hmmm...that doesn't sound right. Have you tried the usual things like switching browsers? (Chrome and Firefox are best...but I've also had success with Edge.) Making sure your browser is up-to-date? Clearing your cache/temp files?
- What are the browser and computer requirements for Instructure products?
- How do I clear my browser cache on a Mac?
- How do I clear my browser cache on a PC?
If none of that seems to help, then I'd recommend reaching out to Canvas Support to see if they can be of further assistance. I'd be curious to know what they have to say...if you happen to contact them.
Keep us posted...thanks!
