### ⚠️ Before posting ⚠️

### Steps to reproduce

1. Install nextCloud Android app.
2. Login to a/your server.
3. Try to open any file.
- Mind that you open the file with an external app (not an md, for instance, in nextCloud itself)
5. Whatever app you open, a "File not found" error will appear.

### Expected behaviour

File opens normally.

### Actual behaviour

File is reported by the opening app as "File not found" (or however else the exception is handled, like in ANYoffice, for instance, "Conversion failed!" -- obviously part of the "open"-process).
