Hi there! I’m sorry to hear you're having trouble completing your payment for the activity in Gdańsk. Since you mentioned trying different browsers, payment methods, and turning off your ad blocker, you've already done some great troubleshooting.

To help pinpoint and fix this, could you please tell me:

1. Are you trying to pay via the GetYourGuide app or the website on your Android device?
2. What payment methods have you tried so far (e.g., credit card, PayPal)?
3. Are you seeing any specific error messages or codes when the payment fails?
4. Is your internet connection stable, or are you on mobile data vs Wi-Fi?

Once I have these details, I can guide you through some tailored steps. But in the meantime, here are some general things you can try:

1. Clear the browser cache and cookies: Sometimes stale data causes issues. Since you’re on Android WebKit, you can clear browsing data in your browser settings.
2. Try the GetYourGuide app if you haven’t already: It can sometimes handle payments better than browsers.
3. Check your card details and country restrictions: Sometimes bank cards have specific fraud protection or country usage limits.
4. Disable VPN or proxy if you’re using one, as this can interfere with payment gateway verification.
5. Update your app or browser to the latest version to avoid compatibility problems.

If these don't help and the payment keeps failing, I can help you escalate it to GetYourGuide's payment support or troubleshoot from the backend, ensuring no server-side issue is causing this.

Let me know your answers on the details above, and we’ll get this sorted out for your Gdańsk booking right away!
