Google Calendar Notification not making any sound on iPhone 6 I am on iOS 12.1.2

I would like to use only ONE app for all my reminders and task management. 

I think Google Calendar fits the bill nicely. Beautiful web-interface, pretty app, reminders, events etc. 

However, there is one problem. Two actually. 


I can't configure a sound for it like I can for Apples Calendar app. 
Even if I allow sounds in Settings > Notifications on iPhone, and set notifications for events in the app itself. I get the notification alright, but no sound. 


Ideally, I would like to hear a sound and be able to configure it.
Try either turning your sound all the way up or actually turning on your ringer for your phone.

If that doesn't work, go into your settings and make sure that the ringers sound is all the way up and see if that works.
