Based on the user reviews of the app "Shipment Tracking", I have extracted the following cons and pros: **Cons:** 1. Difficulty tracking certain carriers, limiting the app's usefulness. ("Can't track some carriers, still waiting for resolution.") 2. Limited functionality for international shipments. ("Doesn't show international tracking details, frustrating!") 3. Advertisements disrupt the user experience, annoying users. ("Too many ads, ruining the app's purpose!") **Pros:** 1. Easy-to-use interface simplifies tracking for most users. ("Simple, intuitive design makes tracking a breeze!") 2. Reliable tracking updates ensure timely shipment visibility. ("Tracking updates are always accurate and up-to-date!") 3. Access to multiple carriers from a single platform. ("Convenient to track multiple carriers in one place!")
