I wish people did more native app development.
And I get it, it feels like native app development is a more expensive specialism, and this particular use case is mostly the customer portal but in an app. But I retain the strong opinion that if you as a company are serious about app development, if you want a good app, you need native apps and native app developers.
Especially if you want to be present outside of the confines of your app - widgets, lock screen activities, smart watches, etc all require proper native components, because they come with very tight memory constraints and just loading in React Native and its JS stuff costs you 80% of available memory budget.
