Rainbow Tour Guides uses modern browser features for sign-in, secure checkout, and messaging. If a page won't load properly, doesn't respond to taps, or checkout fails, an outdated operating system or browser is a common cause. We don't publish a minimum-version list — the goal is simply to be on a current, supported browser.
Quick fixes
- Close and reopen the browser, then reload the page.
- Check whether an operating system or browser update is available (steps below) and install it.
- Make sure you're using the device's real browser app, not a browser embedded inside another app — see Supported browsers.
- If you can't update right now, try a different, more current device if one is available.
How to check for updates
| Device | Where to check |
|---|---|
| iPhone or iPad | Settings → General → Software Update, for the operating system. Update the App Store app itself, then open your browser app and check its own update option if it has one. |
| Android phone or tablet | Settings → System → System update (wording varies by manufacturer) for the OS. Update your browser app from the Play Store. |
| Windows | Settings → Windows Update. Update your browser from its own menu (usually under Help or Settings → About). |
| macOS | Apple menu → System Settings → General → Software Update. Update Safari via the OS update, or update Chrome/Firefox from their own menu. |
If you can't update
- Try a private/incognito window — it skips old cached data and most extensions.
- Try another current browser on the same device if one is installed.
- Try a different device — a newer phone, tablet, or computer — for anything time-sensitive, like completing a payment.

If updating doesn't help, contact us and include:
- Your device model and operating system
