Question:
What is this error on Flow Builder? Webview Error #613: Calls to this api have exceeded the rate limit.
Answer:
There is a limit of 10 saves per 10 minutes if you are using a webview. This is due to Facebook rate limits, and MMIO have to follow. If you don't use a webview button, there is no save rate limit. If you see this error, simply wait for another 10 minutes, and it should save again.
