@421cookies Using a VPN may be the cause for some people, but I am
not using a VPN and the problem is just as rampant.
@Holo @rdn One of the problems appears to be that, if the device's ISP changes, the new system no longer recognizes the connection. For us poor soles who still do not have a permanent ISP for home connection, if the ISP changes, we are immediately logged out of mangadex. Another situation I noticed is that when my cellphone switches it's connection (say when I get home and it automatically switches to Wi-Fi mode), thus changing it's ISP, mangadex will also log out. None of this happened before the new login system roll out. My "Persistent Sessions" list is growing by leaps and bounds!
There must be a better way. amazon.com, which seems to have the very best security, does not log me out when my ISP changes, nor even when I shut off my desktop.
This new system is particularly annoying since I now have the same problem on the 3 devices I regularly use to access mangadex. It's even more annoying when using my laptop or desktop as I have to switch my browser in order to do many things since most of the buttons (post message, upload file, follow, etc., etc.) no longer work on my favorite browser so I am forced to log in twice on the same computer every time I get logged out.
