Just reinstalled Jaikoz after a new system install. (11.6.1 Doves Pro). Accepted my license and is listed as Pro version at top of window. Verified my acoustic ID account number and my Musicbrainz account.
Selected two songs to update and appears to have gotten acoustic ids and musicbrainz ids but did not update Album artist, year or genre. Also, when attempting to match, indicated that 4 (not 2) songs had been matched.
