First of all I'd like to congratulate you for the fantastic app/service you guys provide. I am very glad to be a premium user, as Todoist is by far the best to-do app I ever found.
I'd like to know about the sub tasks issue on iOS devices (sub tasks doesn't proper appear under their main tasks on both iPhone and iPad apps as they do in Mac version). I've seen around the web many users complaining about this since a few months ago and I know for sure that you are trying to fix this. Do you have any idea of when this issue will be fixed?
Thank you very much for the attention and have a great Easter!
