I have been using Webtoon for the past 3 years now and I never face any sort of issue. However starting this month it was showing "Not subscribed" for any comics and "Network issue" whenever I tried to read any episode. But I have subscribed to a ton of them and my network is perfectly fine. And since yesterday I cannot log in into the app. Through the reviews it's visible that it's the problem from the app itself. I hope Webtoon team fixes this issue as soon as possible.
