What's new in 1.0.3:
• Crash fix at launch. Some users were seeing a white screen with a "Cannot read property 'Provider' of undefined" message on app open and couldn't get past it. Fixed.
• Better error reporting. We rewrote how the app captures and reports unexpected errors so we can diagnose and fix the next issue in hours instead of days.
• Reliability guardrails. Added automated checks to our build pipeline so this specific class of bug — a dependency version mismatch between sub-packages — can't ship to the App Store without tripping a CI failure first.
Thanks for the patience if you ran into the launch crash. If you see anything else off, the in-app feedback / support pages now route real diagnostic information to us automatically.
