Unable to Connect

I have used this app for years and thought it was decent.

Last month I upgraded to an iPhone 7 and now Im unable to connect unless connected to a wifi.

I have tried everything, deleting the app and downloading it again multiple times.

The only other work around I have found is going into settings turning off the apps ability to use cellular data. Logging into the app and it says I need to change the data settings and brings me right back to the settings and I turn the data back on and it works for that one time. Afterwards it wont work again.
