• Performance
  Tests on real devices can sometimes be slow due to the availability and network constraints, which can affect the overall efficiency of the testing process.
• Limited Mobile Devices
  While the platform includes a variety of devices, the selection might not cover all the latest models or less common devices, potentially limiting testing coverage.
• Learning Curve for Advanced Features
  Some advanced features and integrations might require a learning curve, which could be challenging for users who are not familiar with automated testing or the specific tools supported.
• Test Timeout Issues
  Occasional issues with test timeouts have been reported, which can disrupt the testing process and require reruns or additional troubleshooting.
