Running elite southern gate map, my skill buttons become unresponsive when boss appears.

What exactly are you seeing?

If this is 'I'm charging a skill when a boss cutscene starts, and have to tap it before I can use it again', then it's already been fixed for the next app update. If it's something else, please describe in detail so we can make sure it's fixed.
