Hm, no - gapless doesn't work on the native apps even when sample rates are consistent. Both the native Cayin app and the native Hiby app - essentially same apps but different skins - have the option for gapless but it's redundant.N6ii has skipping problem with gapless when different sampling rate tracks are played hence why their native apps disabled it.
Not a major deal as UAPP and Neutron have fully working gapless. So it's a software bug that was never resolved on the native apps.
