The 4 in a row has been glitchy for me but you'd think that a new feature would be seriously tested before launching. Very annoying. Missing for 5 days. Perhaps the "improvements " of late of playing with the same folks needs to be reconsidered.
I feel the same way. Either bring it back or lose players as some of us need the help of the boosters to pass a difficult level. I seldom play now that it’s gone.
