Through POWR Facebook Chat, you can easily offer live customer support through Facebook Messenger chat from your Shopify store. Pros: Connect to any Facebook Page from your website and chat through Facebook Messenger chat. This plugin is designed to work on any device and is mobile-responsive. It can be customized with custom images, backgrounds, colours, and fonts. For a live chat app, the feature set is relatively limited. The support isn’t always very prompt. In the event that you decide to stop using the app, it can be difficult to get a refund and remove the code from your website.
