How to link Covid-19 Vaccination certificate to Queensland Check in App Australia iPhone Android

Hi everyone. Since the government has mandated that from today you can't get into certain venues unless you have vaccination proof linked to your checkin app, I thought I'd quickly make a tutorial on how to do it. I did it for the Queensland check-in app but I'm assuming it will be the same for all states. Hope this helps you. Make sure you have the latest version of the check-in app installed, otherwise it might not allow you to link a vaccination certificate (just because you're using the app it doesn't mean it's updated to the latest version - you need to check yourself if you follow my steps and it doesn't work). I know there is a tutorial on the government website but my steps are slightly different and explained in more detail - plus I also show the finger scrolling / pressing which will help in identifying where to press on the screen. I also do it for both my mum's and my dad's phones, one of which is iPhone 11 Pro and the other is a Samsung Galaxy S10e.
