Wrong Wifi

Sometimes, when logging into the POS tablet, it might take you to the settings page directlyand prevent you from going to the main page. 

This is because you are connected to the wrong wifi.

Come out of the POS tablet and click on the threeline icon on the bottom left side of the screen.

Select "Close all" button at the bottom.

Go to Wifi settings and connect to the right wifi

Once connected, hold on the wifi you incorrectly connected to previously

Select "Forget network"

Go back to the POS tablet and check if it is working as normal again.
