You can reset your cache in the Canvas Parent app on your iOS device. Resetting your cache will clear all information on your device that is specific to the app, including login details and app settings.
You may want to use a cache reset if you experience errors when logging in to the app. Because a cache reset will remove app information from your device, you may want to try resetting your password or uninstalling the app first.
After enabling the Reset Cache on Next Launch option, you must force close and relaunch the Parent app for your cache to reset.
