Cancelling Claude subscription renewal immediately revokes Design access

Starting today, Anthropic now immediately revokes Claude Design access if you cancel your subscription plan renewal, even while you're still in a valid period. I had a Claude 20x max plan and cancelled my automatic renewal this month (last week)

On https://claude.ai/settings/billing I see "Your subscription will be canceled on May 13, 2026."

For the past few days I was able to use Claude Design without issue and was actively working on a project. But starting a few hours ago, I'm now locked out with this message:

"Claude Design is available to users on subscription plans." in spite of having 3 more days of "max access."

This feels incredibly gross considering I ALREADY paid for Max 20x which includes Design access. I'm considering a chargeback through my credit card. Does anyone have experience getting through to their customer support? It seems like its all chatbot generated.
