$JUP — I previewed a 100 USDC → SOL swap on desktop without connecting a wallet and toggled “Use V1 transactions.”

The tooltip explains that V1 can change routes and estimated output, and recommends switching to V0 if signing fails. With the switch off, the visible label still says “Use V1 transactions.”

Suggestion: show “Transaction format: V0” when off and “V1” when on, alongside a wallet-compatibility help link. This would make the active format and fallback clearer before connecting.

Read-only review; no swap or signing attempted. AI assisted with wording.
