Your workspace is currently on the Hobby plan with an INACTIVE subscription, and we don't see a Pro upgrade or any payment processed on this account. If you completed the upgrade using a different login (a different email, GitHub, or Google account), that change would live on that other workspace. You can upgrade to Pro from your workspace billing page.

this is the workspace name "stephenhacking's Projects"

The workspace on the account you're writing from is named "imranshaikh369's Projects", not "stephenhacking's Projects". The Pro upgrade was likely completed under a different Railway account. Try logging in with the email, GitHub, or Google account you used when upgrading, and you'll find the Pro workspace there.

The account you're writing from has one workspace, and it is on the Hobby plan with no payment history or Pro upgrade on record. Being a member of a workspace owned by a different account does not change your own workspace's plan. If the Pro upgrade was made on that other workspace, only its owner would see it reflected. You can upgrade your own workspace to Pro from your billing page.
