Move ring not working with exercise ring?

Hello, yesterday I closed my move ring at 11am, 20mins later it said it was only half closed. It started to go up again throughout the day but by the evening I had only just closed my rings? Which is very unusual for me as I had done a 60min workout class and been for an hours walk through the day? Normally I would close my move ring twice doing that. I have tried turning my watch and phone on and off and backing up my iPhone but it’s still doing the same today. I have also updated my watch to the new software any ideas what is going on? Quite frustrating when I know I am putting in the work but it’s not picking it up

thanks
