If there is a legal requirement to broadcast changes (and force acknowledgement) of updated T&Cs/EULA, how best should this be handled?
Sure users will be notified if they HAVE to download the latest version of the app, but this won't explicitly determine whether or not a user has acknowledged the updated terms. I also don't think there's any way to communicate WHY they're being forced to download the latest app.
My question is basically to understand if I need to develop an in-app messaging service to broadcast messages of this nature. Eg "The T&Cs have been updated. Please review the latest version here" and store which version the user has agreed to in the user table.
...Or is there a better (Apple way) of doing this?
