Denon Prime 2, issues after update (Engine Dj 2.0)

With the new firmware update, when slip is active while a track is playing, after 2 or 3 minutes if i touch the jog wheel on vinyl mode, the screen freezes for 2 seconds. Also in the same mode sometimes when i turn on the effect ( i only tried echo mode effect), there is lag maybe half a second for the effect to start. The bahaviour in both cases is similar to when a device is in a kind of sleep mode. Before the update i had no issues. Finally in the previous version you could see the number of tracks in each playlist in the tree menu.

I’ve requested the number of tracks as a feature request, go +1 it here https://denondjforum.com/t/numbers-of-tracks-in-each-folder-next-to-playlist-folders/35739
