I have a Creator app developed to run on an iPad.  We have training events and at the end of an event I want each participant acknowledge by signing on the iPad.  The app opens a form for the first participants who signs, then it opens a form for the next participant, and on and on until all have signed.  It opens each form with an openUrl call.

This sequence of events works fine when simulated on a web browser or in the Andoid app on my phone, but it does not work in the iPad app.  In the iPad app it will open the first and then the second forms in the series, but on the third form it will fail and return to the dashboard.  

Any suggestions would be greatly appreciated.
