Definitely user error/misunderstanding, thanks for the help everyone.

Thank you, I thought I'd read the in 5aixs in body and lens stabilisation work together, but in this case it's all done in lens and when I purchase another lens without OSS it'll be done in body.

Peter, correct lens, they were switched on from the factory but I have tried every position with the same error.

I've just received my Sony A7R IV, 28-105 and 100-400 G lenses and I need to check if something is user error or camera error. Both lenses when connected won't allow the SteadyShot to be turned on ...
