iOS app always refreshes on first launch and often freezes/black screen

I have a graph that’s kinda large (1902 files), and every time I launch the iOS app, I have issues.

It’ll often show my journal view for the day and as soon as I start interacting with the app (open the menu, navigate to the page), it’ll flash and refresh (like it crashes?). Just now it did that and then was stuck on a black screen.

Anything I can do to help troubleshoot this/get this fixed? I’ve tried re-indexing, and it seems like it’ll help for a bit but then ends up in this buggy state again.
