Can't get Gospel Library to update

I just inherited a LG G pad F 8.0. I downloaded the Gospel Library App along with the Member Tools app. The Member Tools works great, but when I click on Gospel Library, I get a black screen saying that Gospel Library is updating, but after a few minutes, I get a popup that says that the Gospel Library failed to download the Catalog and to check my internet connection. How do I get past this so that I can use the pad instead of my phone?

What version of Android is it running? Did you install Gospel Library from the Google Play Store? Do you have any VPNs, web filters, or content blockers enabled that might be blocking the Church's servers? Also, have you tried opening the app while connected to a different Wi-Fi network or internet connection?
