Notifications not working

When I first started using my Fenix 8 I suffered from battery drain as a lot of people have mentioned. I have updated the software which seems to have resolved the issue. 

However, I now receive no notifications at all in my watch, either calls, texts, WhatsApp, emails or even from Garmin app. All worked perfectly fined before. 

I have checked all settings and all are on both on watch and app. I have reviewed all permissions, all granted. No idea what not working!

First time I've had a Garmin, switched over from Suunto, while I think the watch is great, I've been left seriously disappointed with it
