Duolingo keeps logging me out
Since about a week or so, Duolingo is logging me out randomly. Often when I push the 'strengthen skills' button, also often when I've finished strengthening when it's calculating my points, it will suddenly just tell me to sign in without adding the points. It happens so often it's really starting to get on my nerves. I love Duolingo but I can't be signing in again every ten seconds. Has anyone else had the same problem? It's not an 'app' problem as I practice on my laptop. Any suggestions on how to fix this? Thanks!
I don't get logged out, but it does sometimes freeze up on me when I have finished a lesson. It's like it just stops responding and all I can do is quit the lesson and do it all over again. It doesn't happen too often, and usually if I close my browser and then restart the computer, it seems to clear things up.
