Hi @rejoicecorporations, welcome to the Vercel Community!
It seems like you’ve downgraded to v0 Free plan. You can’t use the on demand credits on the v0 Free plan. You must have seen this warning when downgrading to v0 Free from a paid plan.
These credits are not wasted. You can upgrade to any paid plan and make use of them before they expire.
Same for you @goworkspaces-6058.
