Works in Simulator and my iPad, but not on the Clients' iPads!

Oh, what do I do? My app works great on both my iPads and on the Corona Simulator.

When I built a test app and distribute it with TestFlightApp, my clients report that a particular piece of the app does not work. They do “quit” the app, or even delete it, before downloading and installing a new testing version.

I cannot simulate the problems they are having. What can I do to figure this out?

It’s going to be hard to provide any advice without any thing to go on.

So, I was able to discover the problem: I was using a unique ID code based on os.clock(). Turns out, depending on the device speed, and how the screen was built, that timing would, on occasion, not create a unique number!!! However, this never happened on the simulator, only on device, and only when using the app in a particular way that sped up how fast those unique ID’s were created.

Sigh…two weeks lost.
