Why did it happen?
Usually several clicks or page loads in a row, for example opening links quickly or reloading a page that keeps retrying. Sign-in and security steps have stricter limits, so they show it sooner.
What should I do?
- Wait a few seconds without clicking, then try once.
- If you opened several tabs on the same page, close the extras.
- For the AI assistant, the message is different: "You've sent a lot of requests in a short time. Wait … s, then send your message again."
If something goes wrong
- It keeps coming back after waiting: use Report a bug, or contact support in Settings → Help & support, and say which page.
