There are still critical bugs with v2 devices which need resolving. Mainly; Island settings (pre game timer not honored), Matchmaking portals (when art setting enabled no thumbnail shows.), speakers (do not play audio when triggered). All have been reported with the form long ago but still not fixed.
I also have a question in relation to other upcoming changes. What process will happen with MM portals when thumbnails change to squares? Will MM portals in island remain at 16:9 or are they going to automatically be resized to 1:1. This is something creators need to know in advance.
