Our Finance team is upgrading to MS suite 64bit. Is there any known incompatibility between Anaplan Add-in 4.2 and MS Suite 64bit?
No, in fact the 64bit is known to perform better. In the 4.2 release the limit for a saved view was increased from 1 million to 5 million data cells, this was specifically for the 64bit version as the 32bit may run out of memory trying this.
