We have an app in the iOS App Store with a one-time up-front pricing. A company wants to license this app and offer it free or at a discount to their customers. Ideally they want a white label licensing arrangement i.e. our app with their branding. How to do this, while retaining control of our source code? We want to be able to offer a flat fee arrangement (e.g. $X per quarter), or a flat discounted rate per download, or tiered pricing (e.g. first X downloads / month: $Y, above this $Z) Both parties should be able to verify download volumes. If we clone our app (with their branding) and either put it in the App Store as our app or give them the build and they put it in the App Store, can we restrict its visibility or availability to their users? If not, it will cannibalize our current app. Apple's Custom Apps / Specific Organizations program may be an option but it says that "this option is only available before your app has been approved." Thank you in advance for guidance and creative solutions.

My macOS app offers free download and trial, but requires an in-app purchase to unlock full functionality. Currently, only 2-3% of the downloads result in purchase. Presumably the rest either delete the app or keep it but don't use it. I'd like to target such people - maybe after a week or so after the initial download - with a special offer like a small discount on the purchase price. Any suggestions on how to do this?

When I enable resizing of app window in our macOS app, (new?) users get a crash at launch that I can't reproduce. On removing this code, the crashes stop. Symbolicated report below (crashed thread only).

Select 15-20 or more images in iOS Photos app > Export > Save to Files > select Dropbox or Google Drive. Expected behavior is that the selected files should be saved in the selected location. This used to work fine until recently, even for much larger batches. Lately (in iOS 13.x) I either see fewer photos being saved, or duplicates/triplicates, even more copies of a few photos saved. Not sure if the problem is in iOS 13.x, share extensions or in Dropbox and other cloud storage apps’ integration with iOS share extensions sheet.Have tried with iPhone 8 and iPhone 6s using the latest public version of iOS, Dropbox and Google Drive. Haven't checked for other third-party cloud storage services.Please see if you can reproduce this? Would appreciate any ideas on how to resolve this issue.

I am using VNDetectRectanglesRequest to detect rectangular images on a page, and crop them. Detection is quite accurate, but in most cases, the images aren't cropped clean. They have a thin white border around them, as old-fashioned photo prints used to have. Any suggestions? (I get much better cropping with OpenCV, but would like to use Vision if I can improve the cropping results.)
