No Alpha Channels for Photoshop on IPad? (Mobile)

Hello, I have recently been doing a lot of traveling and got photo shop for my IPad, however an absolute massive and essential feature, channels, were not there. This seems to be a massive oversight and it severely affect my work, I am yet to find a work around so for the time being I am unable to do most of my work at all. Please add this feature as it is an essential feature for pros and beginners alike. Thank you.
