Ever since I updated to iOS5 on my iPhone 4, I have not been receiving notifications for Words with Friends Free. The notifications are turned on and data is set to push, but I still haven't been able to receive notifications from Words with Friends Free. Does anyone else have this problem?
Zynga notifications have been spotty at best (also have this issue at times w/Scramble With Friends). As mentioned, this is more of an app issue on Zynga's end...they are the ones that you need to report the bug to.
