In the last few days I've had a message pop up saying 

WhatsApp can't connect using the current  Wifi network. Allow this app to use mobile data

My wifi is working  ok, I can use other apps with out any problems

I have submitted a feedback, with screenshot

Error message back this morning as soon as I opened WhatsApp - BUT -Its because i'm now on works wifi.  Went into settings and changed the  MAC Address back to Use Device MAC and the error message no longer appears!!

So this looks like it's the issue
