Question about Chipolo One

I Can't connect with a Mate 30 Pro

It works on a Huawei Mate 20 Pro

Yes, the additional name "Point" means that this chipolo is linked to the FindMyDevice network from Google and therefore works with all Android mobiles. It is important to have a minimum Android version 9.

It works on all smartphones running Android .....

The main thing is that the mobile has Android 5.0 or higher to be able to install the app "localise".

I think so
Have Samsung
Traker is paired via Google (find my phone)
