I too have been playing for about 5 years, and find this very frustrating. I can play on my Samsung phone, without issue, but because of my large field of play(level 421) it's also difficult.
Almost two months have past since the "E A Valentines update massacre" for Kindle users. why has EA just ignored a giant population of Kindle players, and not fixed the problem . So many of us have played for years, spent real cash on "in game purchases" , and now can t play the game it was meant to be played. We love "The Simpson's tapped out game". E A games, just put it in writing that you will not fix this problem, and we can move on, but not saying anything, makes us hope a fix will be coming. Homer would never stand for this!!!!
Hooray for EA! Latest update did indeed fixed the zoom bug in my kindle fire! I hope all fire tablets were taken care of. And hooray for us having the patience to see this all thru!!!!!
