I am no longer able to run Tasker tasks from Watchmaker. Sony Smartwatch 3 paired with Nexus 6P running Android 6. Watchmaker still receives variables from Tasker, but wm_action('m_task:mytask') commands do not work, from the watch or from the Watchmaker app on the phone.
The same watchface still works on two phones running Lollipop. On the problem phone, Tasker has been set up with beginner mode turned off and external access turned on. I am not aware of any other settings I need to change for this to work, but would be happy to be informed of any.
