Why won’t the app load anymore – Co–Star Personalized Astrology Review

I have been using this app for sooooo long now , and have not once had one issue but now out of nowhere your app won’t load , it says its loading but I let it load for an hour and it still wouldn’t stop loading, I have good WiFi as well as great data and yet this is the only app , THE ONLY APP! That won’t load on my phone and I don’t understand why?????
