Hello,
Just to let you know, ML OS 1.7 and ML remote rendering 1.12.87 have been released on ML Hub if you'd like to give them a try.
Note, when you update to ML OS 1.7, you will need to manually enable developer mode and usb debugging before you will be able to update the remote render viewer application.
This forum post has details on how to enable usb debugging- USB Debugging Disabled By Default (OS v1.7.0)
Best,
Adam
