Just installed the latest 420 version and tested it on both MacOS (El Capitan 10.11.6) and Windows 10.
Trying to open my livesetup (Live 10.0.5) in any of the OS, I’m experiencing a huge delay until Touchable Pro finally connects.
Also Live occasionally freezes for a couple of seconds. From all the tests I’ve done my conclusion is that the Server maybe the cause of it because even if the app is closed on the iPad Pro the problem remains.
For reference trying to open it on Live 9.7.7 (OSX) on a clean set completely freezes Live to the point where it needs to be force shutdown.
This was also happening in the 418 version.
