ChatGPT Internet Search Queries Not Working with Plus

When using ChatGPT-4, prompting the tool to search the internet and provide resources relevant to my query, I get a response: " I don’t have the capability to browse the internet or access real-time data. My responses are generated based on a mixture of licensed data, data created by human trainers, and publicly available data up to my last training cut-off in September 2021.”

I know the tool is capable, and I have used it successfully in the past. I have toggled the settings to ensure Beta features are active, and have seen the issue persist across desktop and mobile UIs. Guidance would be appreciated, thank you!
