[iOS] getPhotos take really long compared to previous package

[simon-klikkie]

Bug

I have recently moved to RN 0.60.5 from 0.59
Previously I was using the CameraRoll from react-native but with the upgrade to 0.60.6 I see that CameraRoll has been extracted and moved to this package.
Previously when I ran this

const cameraRollAssetsPromise = CameraRoll.getPhotos({
      assetType: 'Photos',
      first: 10000,
      groupTypes: 'All'
    });

const [cameraRollAssets] = await Promise.all([cameraRollAssetsPromise, albumAssetsPromise]);

This would return within a few seconds using the old CameraRoll.

But when using the CameraRoll from this package, this promise can take up to a minute to return.

Has this behaviour been experienced before?
Is this just a limitation of the new library, or is this something that can be resolved?

I have similar issue.
For my case, I use CameraRoll from community package with react-native 0.59 and it's fast. However after upgrade react-native to 0.60.4, getPhotos seems to slow down to a minutes.
Happened only for iOS, Android work fine.

Same issue here after upgrading from rn 0.59 to 0.61 and moving from builtin CameraRoll to CameraRoll from community package.
