For a creator under review, I could access the page and add more details.
Now I see that I cannot edit the creator anymore as the page shows: "Creator under review. The page for CZ 🔶 Binance is currently under admin review and isn't appearing in feeds. Check back later — if this is your creator and you believe it shouldn't be under review, contact an admin."
If in the future a submitted creator for review is still accessible, maybe the problem will reveal back.
