DIS Moble iPhone App stopped sending Push Notifications

[peel]

I downloaded the iPhone app a few weeks ago, and at the beginning I was receiving Push notifications for new posts to threads I'm subscribed to, but it stopped working last week even though I didn't change any settings. I read in the Help section that there should be an option within the app somewhere to change settings for this feature but I haven't been able to find it. I did check in my phone's settings and I do have Push Notifications activated for the DIS app. I activated the email option on the boards but I'd rather get push notifications than emails.
Any suggestions on how to reactivate this? Thanks!
