Mobile app iOS v2023 16.7 - Bug during export of vault

When I try to export a vault using the iPhone mobile app (iOS 16.7), the app window closes but the app stays active in the background. Has anyone encountered this behavior?

I could not find any .json file and believe that none was created. However, I am not quite sure. Where would the export be saved and what would it be named?

Any help is much appreciated!

I’m on ios 17.0.1 and BW 2023.9.1 (4890) and the export works fine for me.
The export process prompts you to give a location to put the export file into.
File is named bitwarden_export_nnnnnnn.json (nnnnnn are various digits)
