Illustrator UXP secureStorage persistence discrepancy between debug preview and signed release in version 2023.2

Determine whether the Illustrator UXP secureStorage API is expected to retain values set during a debug preview session in version 2023.2, or if the observed null return indicates a limitation of the unsigned execution path.

The Adobe documentation describes secureStorage as persisting across sessions for a given plugin ID but does not distinguish between debug and release contexts, creating uncertainty for developers who rely on it for token caching while testing locally without production credentials.

Is secureStorage intended to function identically in debug preview and signed releases? Should developers implement a fallback storage mechanism exclusively for debug builds? Does Adobe plan to align the debug‑mode storage behavior with the release implementation in future updates?
