No access to plan/subscription/billing info anymore?

Today it seems that for some reason I reached my maximum usage of o1-preview and I wanted to see my billing, but it is not reachable anyhow! On mobile app it says that I haven’t bought it through APP, but rather through different platform and on web I just don’t have “My Plan” anymore. What’s up?

I second this, I cannot find my plan anymore. I want to cancel my subscription.

Having the same issue. And my phone is directing me elsewhere.
