I am trying to attach a zip file from 3 different browsers, but it's not working.
Falguni, unless you're over 5GB for your zip file (which I'm guessing you're not!) or unless your Instructor set a specific file type (and didn't include the zip file extension), you should be able to submit a zip file to an assignment. Right now since you've tried with three different browsers I'd (1) contact your Instructor and let them know what's going on - also include your zip file so your Instructor can see you really did do your work! and (2) contact Canvas Support to see if they can help - to do this click on the Help link in Canvas and Report a Problem.
Hope this helps! Kona
