#sorry, not sorry


After latest app update, it worked well for several months. Over the last several days, the app will not open, I’ve tried to delete and re-download several times, but after one use, the app won’t open. And this last time, most of my access to books and such were restricted.


Won't load

This app worked well enough until a week or two ago. Now I just get the orange screen that says clinical key and the circular animation that indicates that it's loading. I restarted my phone and deleted the app and redownloaded it. It still doesn't work. Extremely frustrating.


Works great
