Smart lock guest access stopped working and now i cant delete user codes issued to guests

I am in the UK and guest user access was working fine earlier today and now disappeared from my smart things app. I have tried installation again and it says it installed but no longer in the list in the “life” section. I can add it to my favourites but nothing happens when i click it. Also checked the notifications and it still seems to be working in the background as doors are unlocked and the time is displayed in smart lock guest access. How can i delete the codes i issued to my guests when the app wont allow me to? i have paid for 3 licences of lock user management ( for 3 different properties) and can see them in my smart things app. Im afraid to use it until i can delete the codes from the other app. I don’t want conflicts.
