Amazon app now follows the mainstream design pattern where all the most important navigation controls are moved to the bottom. The rest of the design was left almost as it is but this change is already refreshing.
Initially, it was reported more than 3 days ago. The rollout is gradual and it might take some time for this new UI to appear. This is a server-side trigger but you will likely need version 188.8.131.52 to test it out.
How to test:
- Update Amazon shopping app to v184.108.40.206.
- Open the app and check the bottom bar on the home page.
