As I've said before (with a muffled sob in my voice) I'm great with computers but pretty much at sea when it comes to smartphones. And no one in the house can help me. I guess I'll just have to slog my way through this.
Ah, late-life-learning.
Try deleting the app data first. Go to Setting | Apps | WhatsApp | Storage | Clear data
If that doesn't work, press and hold the WhatsApp icon. A menu will pop up. Click X Uninstall.
