SMS disclosure wizard fails every time — "There was a problem creating your text message disclosure"

Hi all — hitting a wall with the SMS disclosure setup wizard. Every attempt dies at the final submit on the "Create text message disclosure" page with: "There was a problem creating your text message disclosure."

Tried 5 times across Sept 25–26. Details:

- Company: Marty's Threads, support email martysthreads23@outlook.com

- Promotional messages checked

- Privacy policy URL: https://martys-threads.shop/policies/privacy-policy (verified live — also tried the pre-filled myshopify URL, same error)

- SMS acknowledgment checked, ToS "generate for me," mobile terms "host for me" with legal acknowledgment checked

This blocks us from finishing SMS disclosure, which blocks the SMS Disclosures block on our signup landing page — so we can't grow our SMS list.

Anyone run into this? Is there a workaround, or does this need Klaviyo to fix it on the backend? (We're on the free plan, so no ticket channel.)
