THE PITFALLS OF IN-APP BROWSERS

Summary from the TLDR newsletter

In-app browsers have limited functionality, privacy and security concerns, inconsistent UI/UX, and worse performance than normal browsers. Businesses use in-app browsers to perform man-in-the-middle attacks by injecting arbitrary JavaScript code and intercepting network traffic. This allows them to watch what users are doing within their in-app browsers. Websites can detect when in-app browsers are being used and offer links to users to open them in the default browser instead.
