This can happen when you are using the Chrome extension.
NeetoRecord’s Chrome extension might not be able to record on certain pages, such as Chrome settings, new tabs, or PDFs opened within Chrome, because these aren't standard web pages. The extension injects its own code into a webpage to capture video, but this isn't possible on those types of pages.
Additionally, some websites, like Facebook or Instagram, or some banking websites may block access to the camera or microphone for privacy reasons.
To bypass these limitations, you can use the NeetoRecord desktop app, which works on all browsers and applications.
