   👋 Hi Anthony (@anthonywhite),

   Thank you for reporting this issue. Here is an AI-generated initial response:

   Classification: Feature request — You’re asking when SPFx will add React 19 support; no broken behavior is reported.

   • Microsoft’s compatibility reference lists React 18.3.1 for SPFx 1.24.0 and 1.24.1, not React 19.
   • Existing coverage: The SPFx roadmap lists planned 1.25 work but does not announce React 19 support or a delivery date.

   What to do now:

   1. Keep react and react-dom at the exact version specified for your SPFx release; don’t use react@latest as a shortcut.
   2. Track the roadmap and release notes for a supported-version announcement.

   Useful links:

   • SPFx compatibility reference
   • SPFx roadmap
   • No sufficiently relevant related issue found in the searched repos.
