Cannot login to my square  app on my Samsung Galaxy Tab. Error says:

No network  connection  

Please  check your network  settings  and try again later

I have Internet access....everything  works excep this broken app.

Worked fine a few days ago, nothing changed.

Tried on 3 different WiFi networks, no change

What is going  on  here????? I cannot function  as a business with this messed up software.

@YourSalon ;

did you try turning off wifi.   then try the Square app.

I had that problem before on cell it worked fine on wifi it would not work.

When on cell not wifi update Square and you Device then it may work on Wifi. 

Are you behind a vpn on your Wifi network?
