Mandatory update for Android and iOS

Before starting of the app, how to get pop up notification for force update of the app. It only needs link of the play store. Anyone knows how to do this?

Thanks in advance.

Did you have run research if this functionality is available at native apps? If not and you use a Backend, you have to create a ApiCall which returns a variable (the minVersion). Than call this endpoint at app startup and check if the version is higher than the current App Version).

So you have to upgrade the config variable if you upload a new App to an Store. In Our App we have on variable for ios and one for android.
