I had this problem a week ago while I was playing on my laptop. I then played the game on my I-phone, I noticed that I had the option to ask friends on my phone. There must be a glitch between laptop/desktop versions and the mobile. Once my friends started to help unlock the next levels, I went back onto my laptop and noticed that the 'road block' was there. I am happy to say I'm now on level 653. So try playing the game on your smartphone if you are able to.
