What is the latest bt app version and once downloaded will it auto download a new version when one becomes available
Which BT app are you referring to as there are several?

That is the latest version and providing you have auto updates enabled, it will update. With regards to the mini discs, I don't use them so I'm not familiar with the update process.
Wholehome discs or Complete Wi-Fi? If wholehome then you need the Wholehome app not the MyBT app
