Platform: iOS, 12.4.1

dnd beyond App version up to date

I have few resources purchased in dnd beyond, including the monster manual. When opening on mobile the monsters manual (previously downloaded locally) the app crashes. It doesn't happen with any other resource (PHB, DMG, Eberron, ...)

Any tip?

I’m having the same issue - iPhone 8+, IOS 13.2.3 

some books are crashing my app and others aren’t. 

I am also having this issue. I have 19 different sources downloaded but, only the MM crashes my app when I tap it. I've got an iPhone 8 iOS 13.3.1.

Same thing here with MM

After a month or two possibly after an update the MM content, problem went away. Hopefully it gets solved for you as well with an update!

I too have this issue. IPhone X iOS14.2

EDIT: I have uninstalled the MM content, re-downloaded and installed it and it now opens. Sounds like an issue with the initial download.
