Clearing Cache and Resetting Push Permissions
Reset browser push 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 permission or background worker states. These steps will reset your site's notification permissions, clear your site's storage, and remove our background worker.
