Hello, Nordic Thingy 52!
I am struggling with developing a health training app using Thingy 52.
In the web app repository, there are two types of codes that are polymer and react.

Polymer app is working well when I tried to follow the instructions.
However, it is not working to execute the React app when I follow the instructions.
Even I match my environments with the same version of libraries, it doesn't work.

Please make sure that the react app is working fine.
If there is missing or absent information, please update them to work properly.
Thanks,
