As I understand it, the phone app is still in development? Where can you look at the MVP? I'm trying to find on yours but the links are not working.
If according to the roadmap, the MVP version is should be ready for testing for users since 2019 
Even they should already hit all of their milestone on the roadmap, but where is it? while I see not much featured on the website, this project is already marked as dead.
You are right it is not straight forward project. But I really appreciate all that difficulties we came a cross underway. We are getting more realistic and mature. The development is still going and I hope we will see the MVP soon. Not next week, please wait and keep patience.
