It worked fine on my computer but it's terrible on my phone. It started fine at first but eventually it kept not letting me in no matter how much I reloaded it. So I tried deletling and reinstalling and it l wouldn't log me in through sign-in. I did manage to go through my google acc instead, which worked. Today, I'm having the same problem again. So I reinstall it. This time, not only can I not sign normally but I can't use my google acc either. I'll still use on pc but not on my phone.
