I have been using this app since a long time but just a few weeks back, i started facing this problem of network issue. My network is indeed of a good range and my other apps are working as well... But whenever I open the app, "no network connection" message pops up. It has been up since past few days and webtoon hasn't given any information till now... It is really a good app but this problem is making it really bad :( i haven't been able to use it at all
