When i updated to 15.5.1 all my categories came up as codes...after hours of reviewing and correcting I had my original categories back. Today I updated to the 15.6 and the same thing happened again...I then restored the corrected back up only to discover that when I updated each account, my categories came up as uncategorized...I have about 10 years of transactions...

Please advise before I go online again to update...
