We published issue 1 of our title in December last year, with V16 or 17 tools. We are ready to go with issue 2, which is on V21 tools. My question is this:
If I publish issue 2 to our branded content viewer app, can everyone who already downloaded the app over the last 7 months easily update the content viewer app via the normal 'App Store update' before they can get issue 2 (which was made on V21 tools)?
or do I need to create a whole new branded content viewer in Viewer Builder and submit to Apple?
