Complete error message: At least one valid postage service must be specified. ErrorCode: 21915469.
To sort this out, you should update the postage policy or edit it. Let’s try by updating it:
- Open your policy manager (eBay Business Policies direct link and click on “opt in”)
- Look for the policy you’ve picked on Nembol and update it by clicking on edit, and then on save (in this way you will update the postage info).
- Once done, make sure to select this same policy in your “list to eBay” settings on Nembol (like in the screenshot below)
- Remember to save.
If that doesn’t work, please consider editing or creating an additional shipping policy (even similar) to associate with Nembol.
