Hello @amelyncruz and @Linduh_58. I hope you are enjoying your time here in the community. Are you playing via Facebook? I ended up going to one of the Candy Crush Facebook groups and asking for friends who were actively playing the game. Now that I have them I get plenty of lives.
Also people don't always check the envelope to see if there are friend requests waiting. I try and check it at least once a week and send lives to the people who have asked for it. Also - if most of your friends are at levels more advanced than you, unless they go to a lower level (for example to collect sugar drops) below you - you won't receive a life from them if they click on the send Lives Facebook button at the start of the level - because it will only send lives to people who have already completed that level.
If you dont make sure your wifi is connected and your logged in thru facebook, then your request for a life will not go thru. You will also not recieve one either
