I have been using Canvas since 2012, of late it has become so slow and it's frustrating my students. I can't afford to switch to another platform. It's worse on Microsoft browsers (Microsoft Edge 42.17134.1.0), on Chrome (Version 69.0.3497.100 (Official Build) (64-bit)) and Firefox it sometimes fails to load.
Just to load the screen below it takes ages. It takes ages to open or create assignments etc.
What is really happening?
