As a product owner I would like to know whether the new language switcher overlay is more effective, so that users can enjoy it if it's more effective.
- A/B test in mobile web stable - 50% should get version A (old: simpler-overlay), 50% should get version B (new: structured-overlay)
- Analysis by product owner
As indicated in T127212#2090175, the data with a 90/10 A/B split have been inconclusive. This task is to make the data more conclusive.
