Hey there, thank you for flagging this! Sorry for the inconvenience and confusion here. I can see that you’ve already reached out to our support team, and I’ve escalated your case internally so they can help you with the outstanding balance. For reference, your case number is #2148668.
For Professional plans, invoices are typically charged automatically to the payment method on file. It looks like the payment wasn’t completed before the plan was downgraded to Starter plan. Since the downgrade has already taken effect, you no longer have access to the Admin billing controls needed to manage the outstanding invoice yourself.
I completely understand how confusing it is to receive payment reminders without having a way to resolve the balance from your account. We will also make sure your experience is shared with our team as product feedback.
Since we can’t handle account-specific billing matters through the Forum, please keep an eye on your inbox and continue directly with our Support team to complete the outstanding payment.
I’ll go ahead and close this thread here. Thanks for your patience!
Update: Good news, the support agent has replied to you! They are waiting for your response for the next steps. Please check your inbox when you can.
