You are kidding right ? This one of fastest growing projects on jolla... Developer is making new updates almost every day with new options and bug fixes... You can't expect that everything works in first release... Whatsapp official is around couple of years now and they managed couple months ago to implement futures that you asking for on Windows Phone...so took them years of work...

Open source needs more support from users...
I assume you bought your jolla phone because you like challenges , you like opensource and you like to test / support new projects ? because if you bought it to use only android apps on it than it was better for you to buy original android phone... It will take some time before all apps are natively running on jolla, it will not happen over the night...
