Advanced Security / CyberSecure blocking my business site orofish.com: request denied with no reason given

I'm an Xfinity customer and the owner of orofish.com, a Shopify store for my small business. Advanced Security (CyberSecure) is blocking it for Xfinity customers. Your Website Checker says "The site is currently blocked by CyberSecure."

I believe this is a false positive. VirusTotal shows 0 of 91 vendors flagging the site, Google Safe Browsing and Norton rate it safe, and Shopify support has reviewed the store and confirmed it passes all of their security checks (Shopify ticket 70787246).

What I've done so far:

- Submitted the report form at spa.xfinity.com twice (ticket IH270703521 was "not approved")

- Called Customer Security Assurance (reference IH270704423, escalated to Tier 3, no callback)

- Filed an FCC complaint (ticket 9177718)

The denial email says the block stays "until the website owner resolves the underlying issues," but no one will tell me what the issues are. Can an Xfinity employee please look into this and tell me the specific reason for the block, or have the site re-assessed?
