How is the console version superior? Sure, it's more powerful, but saying that mobile is "vastly inferior" is a bit of a stretch.
Mobile got 1.4 first probably because more people play it. Mobile players would most likely be complaining about not getting 1.4 if console got it instead of us, like console players are doing now, except more people would be complaining because there are more mobile players. Also, mobile was abandoned in 2016, and after 3 years of being stuck in 1.2.4 DR Studios finally updated it to 1.3 in 2019. If mobile hadn't gotten 1.4 until after console did, it would seem like mobile was being abandoned again, with almost 2 years since the last update compared to console's last update being 1 year ago.
My point is, they probably also wanted there to be more fairness between mobile and console, and focus on mobile instead of console because mobile had far fewer recent updates and was lagging behind a lot whereas console was for a while almost identical to PC in terms of content. Plus DR Studios already was very familiar with working on mobile from developing the 1.3 update and didn't have to make very many UI changes, so they could just focusing on adding content.
