After using the app for around 4 days, the app says that there is a network problem even though the network is excellent and all of my apps are working properly. I reinstalled the app but still it has the same problem. I have been trying to log in again and again since the past few days. I had been going through the reviews in play store and many people are facing the same problem. I request the creator to kindly fix the problem. If the problem is fixed then I would say that the app is excellent
