Exported Type UTI's

We have implemented the Exported type UTI to support some file types that specific with our app. When a file with some extension eg. .xyz gets downloaded from Safari and clicked from the downloads section, it flips back to the app and opens the file in the app.

But from iO14, only on iPad and only when the download location is iCloud, the downloaded file when clicked doesn't flip to app. It seems to be broken,

Is anyone else also facing this issue?
