 * Enhancement - Access from document provider independent from locking methods: [#3520](https://github.com/owncloud/android/issues/3520)
 
-   Previously, the "Access from document provider" preference was only enabled if at least one
-   locking method was activated. Now, it has changes to "Lock access from document provider" and
-   is independent from locking methods, just like another preference.
+   Previously, files of ownCloud accounts couldn't be accessed from document provider or
+   Android native file explorer when there was a lock set in the app. Now, a new preference has been
+   added to allow the access when the app is locked which was only enabled if at least one locking
+   method was activated. Now, it has changes to "Lock access from document provider" and is
+   independent from locking methods, just like another preference.
