I've noticed that in the Alpha version of the Android App, the icon has not been updated yet to the Material design guidelines.
So I've taken the initiative and I created it for my own:
The one of the left uses colours from the material colour palette; the one on the right, the original colours.
In my humble opinion, for the sake of keeping the branding, the original colours work better; and do not look out of place in the material guidelines, which is important as well.
If you like it I can provide the needed sizes for the app.
