Gospel Library app freezing

[McPherson]

I have been using the Gospel Library app for a couple of years now. No problems... ever! Now all of a sudden every time I use the app is completely freezes. I have to delete the app and re-download it and sign back in. It works for a few minutes and then freezes again. I am using an iPhone 7plus and is updated to IOS 12.1. I have plenty of memory and I am connected to a strong internet. Has anyone else been having this problem. Is there a bug in the app? Any help you can give me, would be greatly appreciated. I love having my scriptures on my phone, but this constant freezing is driving me crazy!
