Answer 1

Congratulations on your first app! It's a very exciting moment!

Yes, you increment your Version Code when you make an update to your app.

When you were testing your updated version, did you install the apk file onto your device? You might have updated it unknowingly. Google play will therefore detect that you have matching version codes with the app on your device and the app you uploaded and will not offer to update it.

You must always increment the version code when updating an app on Google Play. Your update will not be accepted unless you do.

As for your update not showing up, Google Play takes time to refresh it's servers. My updates have sometimes taken more than 24 hours to be pushed to the device, while new installers get the latest version withing 2 hours usually.
