On Android there is one:

final resolution (?) by runrevmark (runrevmark)
I’ve taken out all support for mobile platforms as they don’t allow GPL software in their stores.
Yes that is necessary but also a strategic issue to think about.
I think with the old support that we had for mobile, and the fact that I have no idea what I’m doing 
it was best to strip it out, hopefully not too many people are upset about it.
We can simply postpone the question till we have a reliable compilation pipeline for the three desktop platforms from the GitHub repo. This is hard enough. After that, the question of mobile runtimes of course cannot be ignored. I have ideas for workarounds, but that’s for later please.
