Got a doozy here and hope  anyone can help me avoid a massive  return      Bought a load of  C9300L-48UXG-4X-M  units and as the lead-times  were really bad and because there was stock in Distribution , and because the switches are basically the same ... I got the  C9300L-STACK-KIT=   instead of  C9300L-STAK-KIT2-M - as I was told they are the same..  but the link does not work, apparently one has V1 on it  , and the other has V2 on it and they refuse to communicate  between them . Is there  anything anyone  else came across..  anything that can be done..  some firmware updates  ? any ideas are welcome ...
