We were lucky and got in, but it seems more than usual did not. I do believe the queue sharing change affected many, especially in this community.
In the past, DVC had a very similar process for registering for their Moonlight Magic events. I got into those by using multiple devices, however many in the community had strong opinions against this strategy. Last year DVC made changes and required you to log in to your account before getting into the queue. Then if you use a different device/browser, once logged in through those, you are placed in the exact spot as your first log in, thus eliminating the use of multiple devices. Needless to say, with that change I didn't get into the event. I just hope runDisney doesn't go in a similar direction.
