We have a family group set up on what's app and the kids forget about the 2 hour time delay so my phone is frequently beeping in the night.
Don't want to turn the volume down on the phone for obvious reasons.
But I could turn my iPad down.
The inbuilt messenger is very good on iPad, but because I don't have that on my phone I can't use it unless I take the iPad out and about.
I'm sure it will come in time.
