--- Comment #2 from Adolf Belka adolf.belka@gmail.com --- The software is free, although to effectively use it you need one of the Sigma sports watches or Bike computers.
The download centre is at https://sigma-download.com/
The problem is occurring with the synchronisation with the Sigma Cloud, which is where the data from the sports watches or bike computers is uploaded to.
To test the sync with the sigma cloud an account for that would be needed. It is free.

I will read through the regression testing stuff in more detail and give it a go. I have never done any of that with Wine before. However I do build other software with update patches so I hope to be able to understand and follow the instructions successfully.
