  • UX development on Android and iOS is completely different.
  • Have to choose one platform at the expense of coverage due to resource constraint.
• Lack of control after experiment payload is distributed
  • Not all users will update app on regular basis.
  • Problem introduced in experiment cannot be quickly fixed.
  • Cannot pause an active experiment.
