SUNYRA draws its interface with WebAssembly, and this browser has it switched off. Reloading won’t change that — a setting has to.
In Chrome: Settings → Privacy and security → Security → JavaScript optimisation & security, and allow it for sunyra.ai. A work or school profile may have this locked by policy; a personal profile, or another browser, will work.
This is usually an old copy of the app cached by your browser. Reloading below clears it and fetches a fresh one. No health information is affected.
