The latest H9 control v3.3.0 crashes on iOS 11.4 on both my iPhone 8 Plus and my iPad Air! The app disappears into the background while starting up and won't come into focus anymore, even after a restart. So H9 Control is totally unusable for me right now!

Hi, I'm sorry to hear that. I've sent you an email and let me know if you have received that. I'll make a new build for you. Let's follow up by emails and fix this issue together. Thank you very much.
