I’m among the lucky ones. I do feel for those that are experiencing issues as I imagine its incredibly frustrating.
I would say, though, that Realmac has been very dedicated to FTP, in my opinion (based on release notes, podcast discussions, etc). Maybe even at the expense of other things (perhaps the blog plugin, for example). There’s obviously some mysteries left though. Maybe 7.1 can get the 1% down to 0.5%.
