So the latest update did not fix this, however, I have managed to workaround this problem by creating a new play station account. If you register as an American and give an American address when going through the sign up in the play station store you will be able to download the U.S. version of the Plex app. This app DOES open in 1080 and does not have any problems, you can also use it with your normal play station account.
Interestingly, I notice the American app is 42mb and the Euro app is 41mb, don’t know what it means but there you go.
