How to fix “Flashing Tiles” issue in Canvas.

Canvas seems to work best in Chrome or Firefox but sometimes if you get the “flashing” issue, it might mean you need to clear your internet cache memory. This is done by doing a force refresh by pressing both CRTL and F5 buttons simultaneously on your keyboard (Mac: Apple + R or command + R) depending on your browser.

Sometimes a simple force cache refresh won’t work and you need to clear the cache by hand.
