Most of features are not working

Searching for previous booking doesnt work. The experience to search for flights is not better than web experience with multiple issues. I love Qatar airline service but you need lots of improvement to improve mobile experience.
I tried to login to privilege club and it keep saying I am already login. It is totally useless for me. Sorry for the negative comments but I am also professional that could have impact my opinion. I had best experience with the airline itself.
