Moto G6 No sound notifications for WhatsApp

[Android Central Question]

Hi all, As indicated above, I can't seem to get any sound notifications on my Moto G6 with WhatsApp. The phone is running Android 8 and sound notifications are switched on in both the app and phone settings. It's now beginning to annoy me as I'm really not one for looking at my phone every couple of minutes like some. Has anyone else seen this issue and, more importantly, resolved it?
