I have been using the tap since mid January and I have never had any problems
Using Google chrome, the tap always works smoothly, although I couldn't collect coins a few times, but it was my mistake)
I wanted to use the app, but it didn't work for me, I don't know what the problem is, after downloading I just see a black screen...
same here. but I recommend using mozilla firefox browser, it works equally stable on both my laptop and smartphone. if the application doesn't install check Android ver on your smartphone, should be at least 5.0
