The only reason other platforms get support is because users from those platforms spent their free time to help others, that's how free, open source internet projects works.

IOS users almost never do that, so whenever you ask for support for that platform you'll feel the love of your own community, entitled, demanding, not willing to do anything on their own, not willing to spend their time on helping others for free. Sure there are exceptions, but those are soo rare, you might as well wait a few months for the support you feel entitled to get.
