@FiiO this is exactly what you should do in this case. Advertising a feature that couldn't be implemented is a really bad business practice.
Those who can return the player, charge a minimal amount for usage, and return their money, or release (don't know when) an updated player, X1III, that supports the advertised gapless as intended to work, and offer a replacement to the current X1II users, for a minimal price.
Or, atleast give us a proper update in the meantime, my player hangs randomly every couple of weeks, with me having to hard reset the player everytime.
Where I live, i paid $117 for X1II, so it's already at an inflated price.
