Bangle.js 2 app loader connection issues

Do you know why I have to disconnect before using the app loader? Looking at the documentation, it doesn't seem that the way that's working is super intentional:

you just need to select Bangle.js 2 when prompted (or from the drop-down in the top left)

Seems like it would be nice to make the app reflect that functionality, even if the watch is paired for notifications.
