POINT SHOULD CONTINUE TO ACCRUE EVEN AFTER ROYALTY IS REACHED
Both my husband and I reached Royalty some months ago and have not receives any points since. We have traveled well over 1000 miles in the interim, but the point total stays the same. Due to this fact, we hardly use Waze anymore. If you want to incentivize your top users to keep on using Waze, you need to remove the point freeze.
Points do continue to accrue even after getting the crown. Your rank changes, and some people make the leader board. However, sometimes Waze takes a while to update points, but nothing is frozen.
