Update to DCS v7.1 to continue viewing service scores

Version 7.1 is now in the App Store!

Along with some improvements (better functionality with dark mode and larger text sizes) and a bug fix (fixed PDF thumbnail view so that a tap actually goes to specified page), the biggest reason to update is that v7.1 HAS BEEN ADAPTED FOR AN UPCOMING SERVER UPDATE.

The server update is being done to fix a problem viewing PDF scores when using the web version of DCS. The side effect is that if you do not update your app to v7.1, in the near future you will not be able to view PDF scores. We don't want that to happen, do we?
