Game clips missing - options tick boxes checked

Hi all.
I have read through the FAQ and recent posts and cant find any mention of this exact issue elsewhere so please be gentle if Ive missed something (im new to this!)
I have tried saving replays from Forza 6 and sharing them but they dont appear in my profile gallery. All photos are there without any issues, its just the clips.
I have tried using Game DVR and also checking on XBOX clips but no joy there either. I read through online and found a common issue was the gameclip box being ticked ‘block’ or not ticked ‘everybody’, so I checked this in settings to be sure the boxes are correctly ticked. They are.
I have managed to import clips to Upload studio through Game DVR, so I can upload them to the one drive to see them that way. It just takes ages to see and share them if its done that way around and Id like to be sure I have tried all I can to make sure Im doing things right first.
Has anyone else had any similar issues or does anyone have advice?
Thanks everyone.
(fantastic effort by the developers BTW. Its a fantastic looking game)
