Worst angry birds app ever!!
This angry birds has so many glitches, it's absolutely insane. First of all, somehow my husband and I got signed into the same account. We have the same player ID and we have done everything we can to try and make us have separate accounts and nothing works. My husband even left a review hoping that the app developers can fix the issue and help us out, but no one really cares if you have glitchy app I guess.
Also, it takes 6 days to unlock each extra bird. We unlocked all 3 extra birds (had to wait a total of 18 days unlocking them). This morning I wake up and login to the app, and guess what! Somehow everything has reset and it's asking me if I want to unlock them. I'm like, really!! Also, there are times when screen just freezes and have to restart the app to play and in the process I loose all the progress from the current level. There are a lot of other glitches too.
All in all, DO NOT use this version of angry birds. Nothing special, just a headache with the number of glitches. If they can't develop a reliable app, they should probably not do it at all.
