Probably the friction on the struts is still a bit much even with the update (I presume Tesla have still left in some detection as the change originally as mentioned up thread likely was to prevent deforming the trunk lid/rear quarter panel when it is misaligned).
May also need to reset the height too (which can be performed yourself also, although probably best to wait for tech answer first so as to not change anything yet).

As mentioned up thread, if they apply a grease, probably best to apply a more permanent heavy grease like white lithium grease rather than something liquid or spray that might dry out.
