I can vouch for this, started with me last night...whether I'm playing an H2H or tournament. Usually on the second hole the flag stick disappears, regardless of cam angle...it's just gone.
Real pain on any approach where the camera doesn't provide you a close up of the green.
On a 3 wood or less as soon as you start moving your target you lose sight of where the cup is.
On a par 5 where you might not be able to reach the green in two it would still be nice to have a clue where the hole is.
I have an iphone 8+.
I sent my email in, haven't heard anything...
