The screenshot window crashes by sharing with Adobe Scan

This is for Adobe Scan Version 20.01.07 on iOS 13.3.

The screenshot window that you open by tapping on the screenshot miniature at the bottom left of the screen immediately after taking a screenshot, where you can edit the screenshot and crop the area to share or save, does not play nice with Adobe Scan.

Every time that I try to share the snapshot with Adobe Scan from the screenshot window, Adobe Scan doesn't see any data. And if I tap first the share button, then Adobe Scan, and then - upon seeing nothing in the small Adobe Scan preview window - I tap Cancel in stead of "Review in Scan", things go really wrong. If I again tap share, then Adobe Scan, nothing happens. I need to tap twice on Adobe Scan for it to respond.

I fiddled around with this and pretty quickly my entire iPhone froze on the sharing menu of the screenshot window. No reaction to any tapping or pressing the home button. I regained control by locking the screen with the power button and then unlocking it again and after that, the screenshot miniature didn't show anymore and the clicking sound when taking a screenshot was also gone. Taking screenshots still worked, but I needed to restart the iPhone in order to get the sound and the screenshot miniature back.

I've confirmed that this wasn't just one of those things by fiddling some more and after two more freeze-restart events I've decided that it's time to report it.

Does anyone recognize this?
What's the proper action to do with this bug report?

Thanks,
