DDj xp1 - rekorbox 6

Hello there, it ´s question straight to you, our pioneer tech guys.

I was till this moment using XP1 running on the rekorbox 5 fine, together with my main controller, however on the rekordbox version 6 (whis is device unlocked version via ddj flx 4) after cusmasing mapping, it always after the restart  of the rekorbox app, mapping dissapears. I do play pro and this quite something I can not deal with before performances. . It´s necessary to buy any of the subscription plan of the rekordbox in order to maintain custom mapping or how it works on version 6? Thank you for the answer. Patrik.
