Here we go with a Tripps special tutorial.
First a disclaimer. (1) Know nothing about relative merits of Tablets V Laptops. (2) If it works remember the competition is about pointless pursuits.
Make sure the WiFi is on. Leave both Tablet and phone on at all times. Don't switch either of them off.
On your 'whatever' log onto. https://web.whatsapp.com/
Finding this is the most difficult bit. it should give you ultimately get a QR Code that looks like this... .
I can only show a reference to it because once you have completed the exercise you get the chats etc.
Save the URL as a bookmark. you will need it later.
Now for the phone.
On the Moto open whatsapp. It will probably open up on 'Chats'. In the top right hand corner tap on the three dots for the drop down menu.
Tap on Whatsapp Web
At the bottom there should be an instruction ..
Tap + to use WhatsApp on other devices (grayed out) forget this area and go look at the top of the phone.
Top right hand corner tap the + sign.
This will switch your camera on.
Use the camera to scan over the CR code on the Tablet. Hold it until the phone gives a buzz.
Providing you said the magic word 'Please' and held your breath that should be it.
Being a novice at this sort of thing making a later whatsapp connection. switch the phone on. and open Tablet with the URL which you saved.
