App crashes when exporting as PDF on iPad

This is an example note

I took this note when I get a bug report on the user forum, which is about exporting as PDF on iPad.


Exception	NSException *	"UIPopoverPresentationController (<UIPopoverPresentationController: 0x1611467a0>) should have a non-nil sourceView or barButtonItem set before the presentation occurs."	0x0000600000e3d740


It works!
