What's Wrong?

My Claude Max plan subscription lapsed because my credit card had insufficient funds.
The plan was downgraded to Free. When I tried to upgrade again with a new card,
I received an error saying I already have an "active subscription" — even though
I am on the Free tier. The system will not let me add a new card or re-subscribe.

Additionally, the Billing page on claude.ai does NOT show any link to the Stripe
Customer Portal, which would normally allow me to update my payment method.
The account is stuck in a broken intermediate state between Free and paid.

What Should Happen?

After a failed payment and plan downgrade, the user should be able to:

1. Add a new payment method via the Stripe Customer Portal (link should be visible on billing page)
2. Re-subscribe to the Max plan without receiving a false "active subscription" error

Error Messages/Logs

when I choose upgrade (only option) in settings/billing, and fill out card information, I got error: "You have a active subscription", my plan is now Free and no button for ReSubscribe. Only Upgrade, that is not working.

Steps to Reproduce

1. Have an active Claude Max subscription
2. Card on file fails due to insufficient funds
3. Account is downgraded to Free plan
4. Navigate to claude.ai/settings/billing
5. Note: No Stripe Customer Portal link is visible
6. Click "Upgrade" to re-subscribe with a new card
7. Receive error: "You already have an active subscription"
8. There is no option to update payment method or re-subscribe

Additional Information

• I contacted Anthropic Support and received an automated response after several

weeks that did not address the issue (screenshot attached)

• The support ticket was effectively closed with a note saying further replies

may not be monitored

• I posted on Twitter/X @AnthropicAI with no response
• This appears to be a Stripe subscription state issue where the subscription

object still exists in Stripe but is in a failed/canceled state, while
claude.ai incorrectly treats it as "active"

• Screenshot of billing page showing missing Stripe portal link is attached
