How to mass remove messages in timeline

Hi, I realised that the latest version of the Yale lock app had begun to mass spam my timeline as shown in the attachment.

How do I go about:

  1. Mass deleting those messages?
  2. Prevent the app from creating messages?


Settings---->notifications----> there you can remove the notification and also enable/disable them


I did not know that thanks, would be really useful to be able to clear all Notifications from the Home screen though!

You can always make that suggestion directly to athom ofcourse

Thanks. I see there is a way to block notifications from “security” category completely. But is there a way to block just an app?
