Browser notifications require two settings: your browser must allow Substy to display notifications, and your personal notification preferences must include the events you want.
When your browser asks whether Substy can send notifications, select Allow.
Open Notifications > Personal.
Choose the personal event preferences you want to receive.
Allow notification permission separately in every browser and on every device where you want browser notifications. Availability depends on the browser and device you use.
Open the notification permissions for Substy in your browser's site settings. On some devices, you may also need to open the device notification settings.
Change the notification permission to Allow.
Reload Substy, then review your choices under Notifications > Personal.
Browser permission controls whether that browser or device can display browser notifications.
Personal event preferences under Notifications > Personal control which Substy events notify you.
