There is not any problem, everybody can play their 5 lives and then go and do something else! There are a lot of interesting activities out there! On the other hand, if you want so desperately to play more, you can just buy lives, so simple! 😂
I had the same problems to several ingredients levels! Sometimes it takes a long time for them to appear! I suppose that there is some algorithm that indicates when they are going to be appeared! I also think that this algorithm differs from level to level! Why this situation is not clear to the players?
