After clicking play on the home screen, the world selection / friend / servers menu lags to the point where it no longer responds entirely. This lag only appears after that the client has been logged into Xbox.

Example 1: Clicking the play button immediately after main menu render, allows the secondary menu to render perfectly well & smooth (as can be on an aging device) for a few seconds before completely locking up and popping up the application is not responding window.
Example 2: Waiting for the client to login to xbox first, then clicking the play button makes it immediately lag and take over 10 seconds to load the secondary menu before popping up the same dialog box after it finally it manages to render 3 frames over the last 30-ish seconds.

Given that this device is starting to age, it's quite possible that newer phones may only feel a little "frame-rate laggy" instead of not responding entirely but this makes the game completely unusable as I have to race to load a world or join a server withing a few seconds for it to not lock up on me. Looking at the ANR report, it says the first input event queued has existed for over 6.9 seconds... These ANR reports have been sent over multiple times but I don't know if you actually use them so I decided to create an issue here as well.

FYI: When in-game or on any other menu than the secondary (world / friends / servers) menu, although not always running at 30fps, it's perfectly playable most of the time so it's not an issue with the hardware being so under powered that it can't render a single frame.
