This is vastly overrated as a "requirement". You can learn to fly safely in Manual mode with zero sim time. I did.
Getting sim time is a good idea; it just wasn't conveniently available for Android when I was ready to make the move up to Manual mode.
Also, it's important to distinguish between being in Manual mode, and flying acrobatics. I fly in Manual mode safely, but I have not tried, nor had any interest in, doing acrobatics.
I'm just a speed demon, and getting the max speed from the DJI FPV requires you to be in Manual mode, so I do that.
Also, yesterday I got a response from DJI Support saying that the FPV Virtual Flight App isn't compatible with Android. This, despite the fact that they had earlier released a version of the sim app that they said was compatible with Android.
It most certainly isn't compatible with my Android, a Samsung Galaxy S20 Note.
