UPDATE: Nope. Does not fix it. Trying the brand new 1.40 Unity integration... (released today)
Since this latest Update, i have a problem with the Controller-Buttons and the joysticks. They are not working proberly anymore. I have to push them twice or 3 times before my game (Elite Dangerous) recognizes the input. Same with the Joysticks. 😕
Where are you finding 1.40 unity integration? The oculus developer download site and the developer forum both say 1.39 is still the latest available.
