After updating my Sony a7CR to the newest firmware 2.00, I can´t set any other shutter speed than BULB anymore. In the app it always switches back to BULB if I set any other shutter speed. I made a video that shows the behavior: https://imgur.com/a/m1Fojob.
Once I set it to BULB, it doesn´t switch anymore, but then the fastest setting I can choose is 1s in "Langzeit" as a workaround, but that doesn´t make sense in most cases.
