When we are rolling out a new update, the two versions are running simultaneously for a couple of days. We do this to give App Store and Google Play time to update the version in their store. However, this also means that the players who have the new version can't raid or view the profiles of the players who have the old version, and vice versa.
The good news is that once enough players have updated the game, this issue resolves itself. We are sorry for the inconvenience this may cause!
