There is a bug in the current version on the iPad if you have your Extra Allowances set to Manually Redeem that will cause the '+' button not to open the menu. There is a workaround available until we can get a new release out. Unfortunately the workaround means you won't be able to use Manually Redeem on the iPad. Follow these steps to use the workaround:

  1. Go to the Settings tab in the app, 
  2. Tap on App Preferences, 
  3. Change Extra Allowances to either Use Weekly Allowance First, or Use Earned Activity First, instead of Manually Redeem 
  4. Now then the + button will work on the iPad.
