One-Time Code login is completely broken — clicking submit on the Sign In block does nothing. The button shows an infinite spinner with zero network requests firing (checked in DevTools Network tab, filtered to Fetch/XHR) and no console errors.
Troubleshooting already done:
- Reproduced in Incognito with all extensions disabled
- No custom code anywhere in the app (checked page-level and global Head custom code — confirmed CSS-only, no scripts)
- Reproduced with a brand-new Sign In block on a brand-new page (ruling out a corrupted/misconfigured block)
- Users are added directly in Softr, not synced from an external source
- Sign In block version: 5.0.8 (visible in the manifest.json request)
Additionally: the Sign In block’s “Log In Flows” summary consistently displays “Password, One-time code” — even on a brand-new block — despite Authentication settings (Users → Authentication) being configured for One-time code only, and despite the block’s own edit screen confirming One-time code only. This mismatch persists across newly created blocks and pages, suggesting the block’s cached/runtime flow config may not be syncing with the Authentication settings.
