Hi Tyrians! The team is aware of the issue currently impacting gems purchases (Steam client only). We have identified the cause and are currently working on a fix. Thank you for your patience! http://pbs.twimg.com/media/FrL2tNiaYAEgZg-.jpg
We're aware of a login issue related to Chromium and are working on a fix. For now, a possible workaround is to add -usecoherent to your command line. The GW2 wiki has instructions on command line arguments if you're not familiar with this process. https://wiki.guildwars2.com/wiki/Command_line_arguments
@xuan78990 @JOKERI95936713 Unfortunately it looks like there's an issue with Steam right now: https://downdetector.ca/status/steam/ We don't have any control over that, I am sorry.
