When I switched from playing in my browser to playing on the app on my phone, I lost a ton of progress on the level I was on. It acted as if I had just done nothing the entire time I was on the browser and was just idle.

Syncing between devices doesn't work correctly in versions less than 5.00.5 (see the other thread).

Please send me warzone mail if you lose progress detailing what level you were on and how far into it you were.
