Tidal Play Queue always full

Hi, This weekend the Tidal play queue has started to be always full, I can play a single track or album but not construct a play queue when using either a Uniqute 2 or Mu-so Qb. It looks like the Tidal app has changed a bit as well. 

 No problem if I use Tidal direct and bluetooth it in, then I can construct a play queue.

Any views?
