Change placeholder loading screen text from `Lorem ipsum` to `loading...`

[Saphereye]

The Issue

During the loading of individual notifications, momentarily, a default screen with Lorem Ipsum is shown, which may be a placeholder text. An alternative such as loading... or similar placeholders would help convey the current status much more clearly to the average user.

Possible Solution

All the texts are saved in app/src/main/res/values/strings.xml. One possibility is to add another string for loading... which can then be replaced in the correct positions.

Your proposed solution is good. Feel free to raise a CR for the same.

An alternative is to use a shimmer effect. If you wish, you can look into the same as well.
