Troubleshooting compatibility issues
If you are using a non-mainstream or older browser version and experience issues with CAPTCHA display or operation, follow these steps:
-
Upgrade your browser. Check if an updated version of your browser is available. The latest versions include improved security and compatibility fixes.
-
Switch to a supported browser. If the problem persists after upgrading, or if your browser is no longer maintained, switch to Google Chrome, Mozilla Firefox, Safari, or Edge.
-
Try another device. Sometimes issues may be caused by settings on a specific device. Try performing the operation on another device to determine if it is device-related.
