### Steps to reproduce

1. Have a readme.md file with a longer text in the main directory of you nextcloud account.
2. Open the android app.

### Expected behaviour

It should display the first couple of lines from the readme file, with an option to expand. This was working well in the last years.

### Actual behaviour

The content of the readme file is always fully expanded (see the attatched screenshot). I need to scroll very far down to reach my files. This makes it very hard to work with the app.
