@fastidious@arrakis.netbros.com can you see this at your end? I am now using @<fastidious https://arrakis.netbros.com/user/fastidious/twtxt.txt>
to see if you are WebMentioned.
And again, nope, this is not working. So, @prologic@twtxt.net, WebMentions are not working between our two pods, when they should unless you are running a version with WebMentions disabled, or vice versa. I noticed our pods versions are different. I am running the latest from master.
