As of a couple of days ago, my lovely dark-themed UPM has inverted its colours. Now it has grey text on a horrible blue-white background, instead of having white text on a black background as it has had for years. It is extremely hard on the eyes at night time, and cannot be used any more while putting the baby to sleep :( I've restarted my phone, but this hasn't fixed it. I can't find any 'theme' preferences anywhere, so I'm completely stumped as to what has happened. Has this happened to anybody...
