Unichat Extension is a free Chrome add-on developed by nguyenphuongdo99 that provides a convenient solution for businesses to send private messages to customers who comment on their posts on Facebook. With Unichat Extension, businesses can reach out to customers without having to wait for their response.

One of the key features of Unichat Extension is the ability to send messages beyond the 24-hour window. Normally, businesses can only engage with customers within 24 hours of their last message on Facebook. However, with Unichat Extension, businesses can continue the conversation even after the 24-hour period.

Installing Unichat Extension is a straightforward process. Simply log in to your Facebook account on the Chrome browser, access the provided link to add the extension, and click "Add to chrome." After installation, reload the YDpage and start using the extension.

It is important to note a few things when using Unichat Extension. If you encounter any issues with message delivery, try reloading the extension or reinstalling it. Avoid installing multiple instances of the extension on the same application and make sure to remove any conflicting extensions, such as MetaMask.

Unichat Extension offers an efficient messaging solution for businesses engaged in Facebook customer care. With its ability to send private messages to customers and extend the conversation beyond the 24-hour window, it provides a valuable tool for businesses to effectively communicate with their customers.
