"Sometimes app crashes, causing frustration and inconvenience when trying to book appointments." 2. "Limited availability of artists and services in certain locations." 3. "Occasional delays in receiving confirmation of bookings or appointment changes." **Pros:** 1. "Easy to navigate, making it simple to browse and book tattoo services." 2. "Wide range of artists and styles available, catering to diverse tastes." 3. "Users appreciate the ability to read reviews and ratings from other customers."
