On my website, quickloadz.com, we use the Facebook Chat Plugin for providing a chat bot. This chat bubble apparently cannot be set to accommodate the iOS 15 tab bar. I added
div.fb_dialog { padding-bottom: env(safe-area-inset-bottom); } to my CSS, yet the chat bubble still appears behind the tab bar. I tried changing div.fb_dialog to many of the nested elements (like div.fb_dialog_content and even iframe.fb_customer_chat_icon) yet the chat bubble still does not move above the iOS 15 tab bar.
