I was looking up squarespace to see something and I’m actually really surprised at all the bad reviews. (But then again most people only review something if they had a bad experience.) I started using squarespace in 2018 or so and since then they’ve only improved. My site runs fine, I pay my bill once a year, & they add new features here and there. It could be better which is why I gave four starts, I wish it had all the same features as Shopify. But obviously it’s not bothering me that much or I would’ve switched. I would try it for yourself before believing these reviews
