Don’t always call the mothership
(On iOS 13.7)
I was trying to use the app where I had poor to no cell coverage, every time I tried to display a local PDF, the app crashed. My suspicion is that every the app opens it tries to contact the internet. With my file being local, there is no reason.

It sounds like this file is local, but are you sure this is not a file shared with you from Document Cloud? We do have a current bug that we are working on fixing where opening a shared file while you are not logged in causes a crash.
If this is a local file, would you be willing to share it with us? We test frequently with pdfs that are local only and it's possible you have encountered a specific document that is causing this issue.
