Describe the bug
When trying to encrypt a file, a popup appears with the possibility to write a password but the popup doesn't scroll and does not let the keyboard disappear to see the whole page. Makes certain buttons on that page inaccessible.

Steps to reproduce the behavior:

1. Go to a file
2. Click on the 3 vertical points of said file
3. Click on "Encrypt" button
4. Try to scroll to access buttons (e.g Cancel)
5. See error - buttons inaccessible

Expected behavior
Either the keyboard should be able to disappear when swipe down or the popup should be able to scroll up.
