Hi Inkey Solutions,
Ensure you have the required admin permissions, use a unique domain name, and select a supported region. If the problem persists, clear the browser cache and try it.
Changing Payment Details After Tenant Creation:
Yes, you can update or add new payment details in the Microsoft 365 Admin Center under Billing > Payment Methods. Replace or edit the card and reassign it to your subscriptions as needed.
Thanks,
