Steve, for what it's worth, I too have a CEM40, a 2021 version, and I've been running my AAPlus with the newest firmware release with no issues regarding polar alignment. Similarly, I had been using an AAPro with the beta releases and with no issues during polar alignment either, so I wonder if this is uniquely a problem associated with a prior version of the CEM40? Which version of the CEM40 do you have?
