Headscratchers / Gundam Build Metaverse

The show implies that the rapid advancements we see have happened between the 'Fighters' era and the 'Divers Era' has occurred in almost no time at all, despite the necessary time skip used to explain the advancements from Build Fighters to Try Fighters. To go from something like the Plavsky Particle System to a wholly digital universe would take at least a couple decades. It also implies that all the shows take place within a couple years of each other, again despite the Time Skip from Build to Try, that part at least could be explained as the Avatars they used in the 'Metaverse Project' making them look and sound younger. How are we supposed to ignore this blatant and massive retcon, even if it is to celebrate the tenth anniversary of Gundam Build Fighters?
