Another update. Looks like they fixed the button bug but broke Left Stick X with the fix. (Or perhaps the left stick was already broken as well before but not fixed? Not sure.)
A customer reported Left Stick X not working anymore on iOS/tvOS 13 2019.3.4f1, which is the version in which the Pause/Menu button fix was made according to the bug tracker.
[A workaround was posted here]( Rewired - Advanced Input for Unity page-119#post-5438304) by @Benzor . I cannot understand why this fix would have anything to do with the left stick X value since these lines of code he commented out are related to buttons. It looks like there’s a button/axis id mixup somewhere deeper in the code
