TL;DR: In an onboarding flow of one of our apps the Debugger shows successful writes (values visible in “Make changes to…” and alerts fire), and even a Create a thing returns a unique ID. But none of these changes ever appear in App data—as if they never happened.
What I’ve already ruled out
• Privacy rules: Double-checked
• DB triggers / dependencies: None that would revert or override.
• Updating an empty thing: Not the case—one target is the Current User (after signup!)
Has anyone run into a case where the Debugger shows successful changes, but the database doesn’t reflect them?
