Hi all,
The store window is set to be appended automatically. Since it has not been appended to your listings, you may want to generate a new token.
If that doesn't work, feel free to file a support case and I'll send it over to engineering so they can investigate why it wasn't added. Just make note in the case that you've already regenerated your token and that it should be sent to engineering.
Trust me...we want to get to the bottom of this=)
