Thanks providing the information. I have logged and tried the validation. It turns out that you are in a multisite setup. Please be advise that validation will only work in the main site. I went ahead and your main site is validated now. I made some changes in your licenses' site assignment too.
Please be aware that the updates in Multisite setup can only be in MySites > Network Admin > Dashboard > Updates. You won't be able to update the theme is it is not active in the main theme. You'll have to update it manually.
Hope this helps. Kindly let us know.
