See how Zattoo moved from separate native TV apps to a shared React Native setup. In this webinar, speakers from Zattoo and Callstack walk through the migration step by step, covering the reasons behind the change, the rollout process, team changes, testing, performance work, and the tradeoffs they faced on the way.
You’ll get a practical look at how Zattoo brought React Native to production across TV platforms, what they learned from early experiments, how they handled platform-specific differences, and how the new setup changed day-to-day development. If you’re working on TV apps across multiple platforms, this session offers a useful reference point from a team that has already gone through it.
