There seems to be a bug in the control window when 2 toys are connected.  A play partner had their Lush and Hush connected and on my end in the control window the float and loop functions were hidden.  it seems that the two of them overlay each other.  Function was normal and all controls were visible. when I was using my Galaxy S10.  I was unable to get a screenshot, but I will attempt to do so next time we connect.
