Lost gapless playback in Tidal

I now get a pop at the end of one track and the beging of the next.

A little more info may be useful.
Tidal Connect, or from within wiim app?
Output to an exernal dac, or rca out so using wiim dac?
Pop / click between every track, or just when sample rates change? Although you state gapless no longer working, which implies within an album, which implies no sample rate change.
