The Light Trail app for Sony cameras was released a few years ago... It is still in version 1.00 and only compatible with two older/outdated cameras, the ILCE-7S and ILCE-5100. This app offers the same concept with what Olympus has integrated into some of it's cameras, called "Live Composite". Even though, you can gather streaking lights through multiple exposures and blending them together in Photoshop, an app like this can help streamline the process. So my question is "Why hasn't Sony done any updates to this app and hasn't made it compatible with more recent model cameras"? It would be nice to have this app compatible with the ILCE-7RM2 and ILCE-7SM2... If Sony isn't going to offer any updates and more compatibility for this app, then just remove it from the PlayMemories app list. It's a big tease and injustice to keep this app up and not go any further with it, as far as updates and compatibility. I want a definitive answer from Sony and not some invalid nonsense answer.
