I work on a product quite similar to this so I would love to check out the competition. However, it seems you want me to "improve" my experience by using Chrome or Safari lol. That's quite an interesting opinion...
We’re referring specifically to the experience within Bricks, not trying to comment on browsers in general. Right now, we’ve optimized for Chrome and Safari simply because we’re a small team and needed to focus our testing.
That said, we definitely don’t want to block anyone out and will take this as a push to improve support for other browsers soon. Appreciate you taking the time to check it out.
