Loss of Hearts and Mic on iOS devices
I have just tried a lesson on my iPad using the web interface and I seem to be in the group which lost the Heart motivators.
However, that is OK except that they have also changed the method of using the microphone for exercises. I used to be able to use the mic on the web interface but now it expects me to download Flash in order to use it. BUT, Apple do not allow Flash to be loaded on iOS devices which means that the speaking exercises are not possible on iPads and iPhones (via the web interface).
I do have the iOS app of course which does currently work but if they change that in the future so that it uses Flash then they will exclude all iOS users from using Duo.
PS the web interface seems to work in all other ways.
