Not receiving any ring or motion notifications

I suspect it has to be a router/firewall issue as all settings on the device and app are configured to alert me if either the doorbell is rung or a mtion alert is triggered. Everything else works fine, live view etc.Ive never received any alerts from day one, but not really got around to doing anything about it. But the front door is getting busier with the postman trying to deliver stuff!Have reinstalled app, and checked phones permissions etc, but cant see anything obvious.
