I use WhatsApp and currently it won't let me log on and use it.
Things I've tried so far:
deleting and reinstalling the app.
turning my phone off and back on again.
putting it in to and out of airplane mode.
None of these steps have worked. I've read resetting network settings might help but I'm unsure what that would do to my phone overall.
Is there some way to diagnose what's going on with WhatsApp and fix it?
