Problems with software? With app? With ME?
I having been trying all day to access Duolingo on my phone, as I have been doing for the last 4 years. Either lessons won't open at all, or they open for a split second and then the whole app shuts off. Is it just my phone, or are others having this problem? It seems to have been building for some time: lessons take longer and longer to load, and there have been frequent lessons telling me to 'Write what he said' or 'Translate what he said' but there's no sound. How can I get around this to be able to do my lessons?
How old is your device and the OS version?
I could imagine that the recent IOS app changes might not be tested very well on older versions?!?
As there are more users complaining in general about the apps, I think they are adding more and more un-tested / unreliable stuff which simply does not work that smoothly anymore (I first time heard complains about the Duolingo facts popup windows and how lessons are now endlessly loading or not at all).
