I've requested level unlocks from friends, but I receive new lives instead. This is not the first occurrence, it has been happening for the last few levels.  I just finished level 470, trying to cross to next level.

This has happen to me when I ask several friends at the same time,, when I ask one by one I get the help to pass the level,, hope this helps you
