Hope you're doing well today!
If the first, you can login to your account at any time to access any outstanding orders. Otherwise, you will need to select a paid plan in order to access your admin. That said, once you re-select the paused plan, your account will be credited for that subscription charge, which will be put towards a future bill whenever you reactivate your store. If you do have any questions or concerns about your account or billing, you are welcome to contact our support team via our Help Center here at any time. Please let me know if you have any questions!
