I've been a long-term mcpro24fps and a user of Filmic pro before that. It's a great app, no doubt about it. The issue is not the app, but the OEMs who makes things difficult, artificially limiting the capabilities of the devices and even removing features in updates. Nothing is consistent and each device works differently from the next one, even from the same manufacturer. A long running joke in the McPro24fps Telegram chat is to never upgrade!
