How to force an app update?

Question

React Native

There is a working application for IOS and Android. We are releasing a new version that is radically different both in terms of api and webview screens.
How to make the user update the application, because. won't the old one work?

Answer 1

As I see it:
Compare the user's version with the one in the store.
And if an update is required, then display a window with a transition to the update, preventing the application from being used.
But that's just thinking out loud.

Answer 2

compare the versions of the application in the store, for example, and if there is an update, show a stub on top of the application - "update", and that's basically it.
