We are seeing some issues with different iPad models right now that we are trying to fix. There must be some subtle differences in what the difference GPUs on these devices support that we haven’t quite figured out yet.
This is our current top priority for iRhino as we don’t want to make any sort of public announcement about the app until we have this fixed.
Can you share which exact iPad model you have? This can be found in the general settings for your iPad.
