Thank you for reaching out to the Community! I’m happy to provide some assistance with purchasing shipping labels, to ensure this gets resolved.
To share some context, we are currently aware of this issue impacting label purchasing and actively working to get resolved. For updates, you can check out the Shopify Status Page as we will be bringing any new information there.
As I can completely understand how this may not be ideal, we recommend purchasing shipping labels directly from a third-party vendor for the time being to workaround around this.
Please let me know if you have any other concerns.
