Having played Bloxburg for the better part of six years, I personally never batted an eye at or had a problem with the UI we had. 

When I began playing regularly I learned how it all worked quite quickly and was content with it. My contentment was, I believe, shared by the majority of players and I for one cannot give one instance let alone hundreds where a new UI was requested. We asked for a new map, not a new UI (yes I know a map is being worked on).

While I have appreciated many of the updates given to us by Coffee Stain, it is undeniable that this update is on the level of the infamous job pay update. In fact it may even be worse. 

The job pay update affected most of us, those who worked regularly for money. But it was avoidable by just not working (albeit the fainting feature was less avoidable); but this update quite literally has an effect and impact on anyone who joins the game. You are immediately presented with the new main menu UI (which, I must say is probably the best part of this awful update). Then as you play the game you of course have the complicated UI in front of you all the time and of course the copied mobile phone from any other roleplay game.

It's also worth mentioning, although these may just be bugs to be fixed, that the player leaderboard at the right is gone and there is no stamina bar when you sprint. If the leaderboard was purposefully removed, I really see no reason why it was and it's a little thing that annoys me most out of this update.

I really did not see any problem with the old UI (but I will digress I'm speaking from a solely desktop viewpoint, I have only played mobile Bloxburg a handful of times but even then I didn't notice anything different). 

Coffee Stain, please listen to your community's pleas and don't let history repeat itself.
