Hi Reconwhispers ,
Thanks for reaching out to us! I hope that you had a great weekend. 😄
Could you take a look in this page and see if your subdomain's url fits in our list of working subdomain url scheme?
If so, then perhaps the buttons not appearing on your subdomains could be due to something else.
Could you maybe make sure that Buttonizer is integrated through the plugin or snippet on the subdomain?
Please let me know! 😃
