Ionic 4 App still runs an older version after being installed on devices - Note I incremented the version

Hello everyone,
I am developing my first real world app but am having an issue after first install to the test devices (iOS and Android). The issue is after install, the app comes up as I am expecting, but once I shut it down and reopen again, it comes up as an older version, without the latest updates I made. For android when I delete the app cache the issue is fixed but comes again once I re-open later.

When I build I first run “cordova plugin save, cordova platform rm ios/android, cordova platform add ios/android” commands and I delete the www folder, but none of these has helped, please share the solution if you have came across this.

Here is my ionic info output:
