Ionic version: (check one with “x”) [ ] 1.x [ ] 2.x [x] 3.x

I’m submitting a … (check one with “x”) [x] bug report [ ] feature request [ ] support request => Please do not submit support requests here, use one of these channels: https://forum.ionicframework.com/ or http://ionicworldwide.herokuapp.com/

Current behavior:

Clicking tab buttons in the tabs component does not trigger App#viewWillEnter and other lifecycle events, except the first time the page is being loaded.

Expected behavior:

Every time selected tab changes in tabs component, lifecycle events get triggered on each tab’s view.

@Creawebs - we are not planning on having any more v3 releases of Ionic. You will need to retest this in v4 when it is released and then create a new issue if it is still a problem. The first BETA for v4 should be soon (within a few weeks).

That is a very important statement @Creawebs. I really wish this would be announced properly on the Ionic Website or blog. You are effectively ending any and all support for Ionic 3 (and previous), even before Ionic 4 is out. This is a very important decision that really ought to be communicated honestly and openly with everyone in a proper manner. Why even bother filing or commenting on v3 tickets then?
