Any thoughts or research on forced updates on apps?

I was wondering the UX impact on forced updates on apps and found little to no research on the subject so far.

There may be crucial information that needs to be accessed in certain cases but an abrupt forced update may block the users from accessing that information especially in no wifi areas.

I'm working on a travel app that contains ticket information and I'm afraid that this issue might severely damage the user experience in such occasions so I'm looking for anything to back me up here.

Is there any data/research on how often do apps from different domains release forced updates and what are their impacts etc. and what are your thoughts about this subject?

Thanks!
