I noticed several UI improvements in the latest update:
Online lobby loads much faster now.
Games load much faster now.
Game is now fullscreen on my phone (whereas before it was letterboxed).
Player profiles load faster now.
Really makes a difference!
Card animations are also way more fluid and crisp for me.
The game loads much more slowly on my current-generation iPad. Additionally, the game no longer renders correctly for aspect ratios wider than 16:9.
Also noticed the game absolute shreds battery on ios devices post-update. Both my ipad and iphone get superhot when playing TTA - which is weird given im looking at a largely static screen
