What happened? – Lippincott Nursing Advisor Review

I have had this app for a little over 6 months with no issue. I upgraded my phone from 6s plus to X and the app will no longer open any content. I can still search for diseases and medication, but no content is provided. Very helpful in the beginning but now very disappointing.
