I’m experiencing the same issue reported multiple times since December 2025: quota tier shows “Unavailable” despite active billing. Project: Adlumina (gen-lang-client-0182242601) Billing: Active since March 23, €64.36 spent in 7 days Model: gemini-3-pro-image-preview (Nano Banana Pro) Error: Tier shows “Unavailable” in AI Studio This is blocking a production application with paying customers. I’ve seen others report this issue resolved itself after 2 days (Aw_Thr), but others still stuck after trying all solutions (Zijian_Ma, eazyly). Can a Google employee investigate and manually fix the tier sync? Thank you.
