We study the unitary dynamics of the bosonic quantum East model, akinetically constrained lattice model which generalises the quantum East modelto arbitrary occupation per site. We consider the semiclassical limit of large(but finite) site occupancy, so that the dynamics are approximated by anevolution equation of the Gross-Pitaevskii kind. This allows us to numericallystudy in detail system sizes of hundreds of sites. Like in the spin-$1/2$ case,we find two dynamical phases, an active one of fast thermalisation, and aninactive one of slow relaxation and absence of ergodicity on numericallyaccessible timescales. The location of this apparent ergodic to non-ergodictransition coincides with the localisation transition of the ground state. Wefurther characterize states which are non-ergodic on all timescales in theotherwise ergodic regime.
