Installed the 67 Designs driver side phone mount with adhesive and screw. Seemed pretty solid at first, but now there is a lot of movement from the base mount ball. The base is on solid but the ball mount moves around independent from the rest. Is there a bolt on the bottom of the base that would allow me to tighten the ball? Don't want to take out the screws and rip up the adhesive until I've heard back from 67 Designs customer service, which I emailed early this morning.
