Hi there! I see you're having trouble logging into your BudapestGO account on your mobile with a "captcha failed" message. Let's get to the bottom of that. Just to clarify, are you using the BudapestGO app or trying to log in via a mobile browser? Also, have you tried completing the captcha multiple times, and does it fail right away or after a delay?

Meanwhile, here’s a step-by-step approach we can take to resolve this:

1. Restart your device to clear any temporary glitches affecting the captcha.

2. Check your internet connection—switch between Wi-Fi and mobile data to see if one connection might be causing issues.

3. Ensure your mobile's browser or app is updated to the latest version. For browsers, BudapestGO works best on Chrome or Firefox.

4. If you're using the app, try clearing its cache and data via your device settings. On Windows (if you use a web-based app), clearing browser cache helps.

5. If the captcha keeps failing, it's sometimes due to cookie or JavaScript settings. Make sure they are enabled in your browser.

6. Also, if you have any ad-blockers or privacy extensions enabled, try disabling them temporarily as they could interfere with captcha scripts.

If these steps don’t help, let me know which exact browser or app version you are using on your mobile device. We can then dive deeper, possibly checking for known server-side issues or adjusting app permissions.

I’ll be here to guide you through each step! Are you ready to try these out?
