When feature flags ignore app versions, things break

In this talk, the speaker examines a common but overlooked failure mode in experimentation systems: enabling feature flags without accounting for mobile app version compatibility. While backend systems may mark a feature as on, older clients often lack the UI paths, data handling, or safeguards required to support it, which results in incomplete experiences and hard-to-diagnose bugs. The session explains why mobile environments amplify this problem due to delayed updates, long-lived sessions, and version skew between clients and backend services. It then outlines practical platform design principles for safer experimentation. Attendees will leave with a clearer understanding of where feature flags quietly fail at scale and how better platform design restores trust in progressive delivery.
