Ios document picker does not save files


every time I use the new document picker in an other app, all changes were not saved after I closed the document.
This behaviour is reproducable with textastic and word for ios.
Opening a document with the document picker is no problem.
Creating a new document and save it with the document picker results in an emty document.

Saving the document picker with the app “Trasnmit” (nextcloud as a webdav server configured) is no problem.


Would you mind opening an issue at github?
Looks like an bug and should be reported. Thanks.
