DuoLingo Speaking Delays and Problems...
Sometimes, when I practice a skill or try to strengthen one, the sound is delayed. This is a problem when it says, "Type what you hear". I have to wait for a very long period of time before I can do the question, and I am afraid it will take away time on timed practice. Sometimes the sound buttons don't even work until a minute or two.
This happens to me a lot in Firefox. I shut Firefox down and restart it . It works normally after that. It usually only happens to me when Firefox has been open for a couple hours or more.
