Does NOT Work!!! – AT&T Landline Texting Review

I added LandlineTexting to my business for convenience of communicating with my customers. This app was how I should be able to communicate, but No. In iOS 11 it opens and immediately closes. So far nothing from tech support. I’ll be cancelling my LandlineTexting if I can’t use it other than on my desktop.
