@Frankie1981 Not sure if you remember the details in the Beta notice but it is not automatically downloaded. You need to go to Settings > Software update > "Download and install". The Beta software should be there for download.
Hello @Frankie1981 ,
Updating to beta software from AUIN software is currently not possible. It will be available from our next beta software update release. Please try once next beta software update is released.
