Scrolling breaks when I delete and re-add platforms

Hi, I’m running into a bit of a strange issue. I finished my ionic app a few months ago and am about to submit to the iOS app store. Unfortunately I need to rename it, and I’ve been unable to do that without corrupting the Xcode file. Reading what others have said, I need to delete the platforms folder and re-create the Xcode project.

However, when I do this, the resulting app does not allow for “normal” iPhone scrolling – ie a slight bounce at the bottom of lists etc. I did recently update my local version of ionic, which might have something to do with it. In addition, my config has the following preferences:

  <preference name="webviewbounce" value="false"/>
  <preference name="UIWebViewBounce" value="false"/>
  <preference name="DisallowOverscroll" value="true"/>

Would really appreciate some help with this. Let me know if you have any ideas! Right now what I want is for each of my tabs to scroll iOS-style
