I'm a bit puzzled. I can't find anywhere to link the Mobile App being targeted to a push delivery template. This option doesn't appear in the template advanced configuration anywhere.
The result of this is that every time one of my users creates a new push message from any push delivery template, they have to manually select the mobile app they're targeting from the dropdown.
I'm sure I'm just missing something. It would be a really odd oversight to not have the functionality to configure this in a template.
This has been accepted as a bug by Adobe.
You can duplicate an OOB push template and configure with mobile app etc.
When you come to use the template to create a push, the Associate a mobile App to a delivery is not inherited from the push template
When you go back to the push template the dropdown has disappeared from the UI
