are you allowed to place a "send feedback" button (which would, for instance, open up a mail to app support) in your iOS app?
I recall reading on one of the App Store submission procedure docs and / or UI guidelines that you're not allowed to place a custom "send feedback" form (or button?) in your own app as users should be using the App Store review mechanism instead. However, I can't seem to find this anymore, so I'm not sure if this is still valid.
Does anybody know more about this? It seems an obvious way to (hopefully) get users (even dissatisfied ones) to cooperate with you and prevent them from writing angry reviews without you being able to reply at all.
I have included a "Send Feedback" button in a few apps in the past that opened the email modal without any review issues to date.
