Hi folks, apologies if this has been addressed.  Twice now I've been out flying with a 2 Pro and have tried switching to 120 fps.  I tap the icon, the indicator over to the side of the menu blinks to 120 for a split second, then back to 60.  Then I go home and fire up the drone in my office, and it successfully switches to 120.  This whole scenario has played out twice.  Any help appreciated.  It's a Sandisk U3 V30 card.
