Clearing Cache and Resetting Push Permissions

Reset browser permissions and data

Even if your settings are configured correctly if you had previously used incorrect settings, push notifications may not work due to invalid permissions or background worker states. These steps will reset your site's notification permissions, clear your site's storage, and remove our background worker.

What happens when I clear browser cookies?

When someone clears their browser cache/cookies/history, this prevents the browser from getting all push notifications from sites to which they are subscribed.

When this happens, it wipes all data about the user, like the browser key. This is stored in the IndexedDB of the browser.

Clearing browser data does not reset push permissions to the website. When a user, who has cleared the browser data, returns to the website, the iZooto SDK check the permissions and if push notifications are allowed, it automatically resubscribes the device to push, which creates a new push record (browser key).
