Just changed my subscription to unlimited but still asking to upgrade to use charts

I have just upgraded my subscription to unlimited but when I tried to access charts its still asking me to upgrade. Is this something to do with the billing period, I was paying yearly but changed it to monthly but from what i saw it says I should have access from today. I did see some other similar posts most of them were saying about multiple accounts, as far as I know I only have one account so don’t think that is the issue.
