Notifications

Push is optional. Turn it on from Inbox or Settings.

If nothing arrives

Allow notifications for Klikol in the browser or Android settings. The app cannot override a system block.
If the side menu says notifications are blocked, open the browser/site settings and allow them, then reload.
Battery savers on Android often kill background push. Exempt Klikol.
Web push on iOS Safari is limited; the Play app is more reliable on Android.

Signing out stops push for that device.
