My follower won't pick up items [closed]
Solution 1:
Do you have any customized controllers, particularly the activate command? If so, this reddit thread mentions this might be a bug on the Switch version of Skyrim. Followers do not seem to pick up items unless the activate command is the default configuration, that being the A button.
Try resetting your activate command to be the default. A user on the reddit thread confirmed this was a solution for them.
