Unable to refresh snaps on brand store

Hi, I have created a signed ubuntu core image with prepare device hook. But when I try to run snap refresh “brand store snap”. It just returns

error: snap “brand store snap” not found.

I am not sure how to get it to work.

in snap refresh "brand store snap" the “brand store snap” is a placeholder for a snap name from your brand store i guess … you should contact your Canonical field engineer with a few more details …

Thank @ogra . I will. I have added a case on the support store.
