A7Rii frequent lens disconnection (losing auto focus and F stops)

My 3 years old A7Rii is now occasionally experiencing a strange disconnecting problem with the lenses. Sometimes when I switch on the camera, the F Stop sits at "F--" and it doesn't allow me to adjust it, auto focus is lost and the auto focus bracket on screen is inactive. Have to switch it on and off and sometimes further tighten the lens to get the F Stop values back and make auto focus works again. I have noticed that this problem also occurs when I turn my camera from landscape to portrait...

Having read from the forum and tried alcohol swabs to clean the contacts near the sensor, this problem still persists.

I have just ordered a brand new E-mount metal rim, not sure if it helps though.

Has anyone experienced a similar problem and manage to come up with a solution before I spend a fortune on the A9????????

(The problem occurs to my Batis 25mm and 85mm which are both near brand new).
