At the beginning of December quite a few people complained about losing the offer of extra moves after failing a level @MrsTJ, but the complaints soon died off. When things like this first occur it is never clear if the change is part of a test or a change that affects everyone.
If we start to see more complaints about the issue then we can conclude that the extra moves have been removed by King. If we don't see anyone else complain about the issue then unfortunately all we can conclude is that your game is no longer part of the group that receives extra moves.
