I heard Huawei's HarmonyOS is planning to drop support for Android compatibility and currently doesn't have a lot of native apps. What SDKs support it, and what tools do you need to test for it? I'm especially interested in whether any of the big game engines like Unity or GameMaker can be coaxed into working on Harmony. Please share any information you have!

No experience, doesn't look like any western companies support it yet. This is their website. If the English version doesn't pop up, there's a drop-down at the very bottom of the page.
Here's a course on HarmonyOS.
