App stopped working entirely. – Workout Anytime 24/7 Review

I just recently downloaded the latest, current version of this app (It's still on my phone and I'm only given the option to "Open" it through the app store; No updates are available). It was working fine for a few days, and I loved having my membership card on my phone, but now when I open the app, I'm given a single screen that says "This app version is no longer supported.", along with a Facebook button in the lower-left. I'm using an AT&T, 128 GB iPhone 6s with iOS version 10.2.1 (same version I had when I downloaded the app). Please update this app soon, because when it actually worked, I enjoyed it fairly well, excluding my home town gym location not being listed in the app, though it did open very shortly before I downloaded the app. Thanks!
