Unable to manage Joplin Cloud subscription / payment

Operating system

macOS

Joplin version

3.6.15

Desktop version info

It's not about the app, it's about Joplin Cloud subscription / payment.

Sync target

Joplin Cloud

What issue do you have?

I signed up for Joplin Cloud 2 weeks ago and after the 14 days free trial, I think Stripe tried to charge my credit card and failed. I received an email with the message

We were not able to process your last payment. Please follow this URL to update your payment details: Manage your subscription

But clicking on the link gave me:

Your account is disabled for the following reason(s):
Subscription cancelled on 18 Aug 26 03:25:17 (UTC)

And the help section just sent me down the "manage subscription" -> "Could not find subscription" loop.

The credit card is valid and I can also pay by SEPA Direct Debit. But I'm unable to update payment methods as it looks like my account is disabled without warning.

Looks similar to this issue. Please help, thanks!
