Same. Lots of bugs and no fixing or accountability. I have stopped recommending Squarespace to anyone for the last year or so. I fact I advice them to get something else....
When you try to approach support about the issues and bugs you just get told off with some standard answer and absolutely nothing actually happens.
It's been well over a year of me filing my first bug complaint and that same issue is still there. Since then I have been running into several more and just yesterday I ran into yet another annoying bug when I had to help someone with their site.
Maybe it's time for me to find an alternative and migrate...
