Hi there! I understand you're having trouble creating a Knuddels account because it gets stuck at "sending pin." Let's see if we can get this sorted out together.

To start, could you tell me a bit more? For example:
- Are you trying to create the account on the Knuddels app or via a web browser on your ChromeOS device?
- Have you checked if your device has an active internet connection when you try to create the account?
- Have you waited a few minutes, or tried to resend the PIN code?
- Did you enter your phone number or email correctly for receiving the PIN?

These details will help me guide you better! Meanwhile, here’s a general step-by-step you can try:

1. Check Internet Connection: Make sure your ChromeOS device is connected to a stable internet source—Wi-Fi or Ethernet.

2. Restart App/Browser: Close the Knuddels app or browser tab and reopen it to try the account creation process fresh.

3. Clear Cache (if using browser): Since you're on ChromeOS with WebKit browser, try clearing the browser cache to remove any old data that might interfere.

4. Allow Notifications or Permissions: Sometimes, apps require permissions to send you a PIN code via SMS or email. Check if the app/browser has the necessary permissions.

5. Verify Contact Info: Double-check the phone number or email address you entered for the PIN.

6. Try Another Network: If possible, switch to another Wi-Fi or use mobile hotspot to rule out network restrictions.

If you've already tried some of these, please let me know which ones, and we'll dig deeper!
