A big feature for our app is that it needs to work in spotty network conditions - especially as we've expanded internationally, and as students are now studying from home where they often don't have WiFi.
We have a redux store where we keep our data, and much of the "have you watched this video" or "have you completed this assignment" data gets persisted to disk, so if a network failure happens we can just try again when the user's device is back on!
(Does that answer your question?)
