iOS 11 - FastPDFKit long delay when calling MFDocumentManager's outline function

I am testing FastPDFKit in our current app on iOS 11 beta 3. Assuming documentManager is a properly initialized MFDocumentManager object, when I do this:

NSMutableArray *ol = [documentManager outline];

there is a 2 minute delay that blocks the thread it is called from. On iOS 8 - 10, there is no delay.
Any chance there will be an update to fix this problem before iOS 11 is released?

EDITED TO ADD: During the 2 minutes, the device CPU is at almost 100%.

    sorry for the delay.

    I can confirm that we are aware of this minor issue and we'll release a maintenance update for iOS 11.

    We aim to release it in the second half of August in order to ensure compatibility with an iOS 11 beta version close to the final one.

    Makes sense. I'll watch the GitHub project so I get notified when it is available.
