More countries adopting or switching to Apple/Google contact tracing API.
Finland, Ireland, and Portugal are adopting it; Austria is switching to it; Singapore and Australia are both
considering making the change.
Switzerland was the first country to release an app based on the API, with Italy following close behind. Germany, Latvia, and Estonia are doing the same, with only the UK and France having rejected it for now. Germany made a U-turn from its original position.

Even till now they are still only considering...by the time they consider finish, maybe next year already

Sometime first to do something is not always good when you wait awhile more you have better choice. Switzerland smart, never create their own way of doing things and instead wait for Apple/Google finalise their API and launch their app.
