Sandbox subscription deactivated without a reason; API Logs empty

My Stringlive Sandbox subscription was deactivated twice without an explanation.

Subscription ID: e3f2db92-5248-4c21-9f75-408cfb20552b
Created: 2026-11-05T03:29:38Z
API version: 2026-09-16

Current plan pricing is STATIC MONTHLY: USD 499 cents for one period, then USD 999 cents indefinitely.

The subscription returned ACTIVE at creation, but later became DEACTIVATED. Both DEACTIVATE_SUBSCRIPTION events omit info.code and info.detail. There are zero attached invoices. Manual reactivation was followed by deactivation again.

The Sandbox Dashboard displayed “1 month free” and $9.99, although our creation request did not explicitly specify a trial or price override.

RetrieveSubscription in API Explorer successfully returned HTTP 200. Clicking View logs still showed zero results, including after waiting and refreshing with Sandbox selected and the search empty.

Can Square investigate the deactivation reasons, explain the free-trial display, and help locate the missing API logs?
