Hi Matt
I use SEMRUSH (https://www.semrush.com/) to co-ordinate SEO activity for a number of Squarespace sites I maintain.
When I run the SEMRUSH site audit tool, I notice the same warning coming up regarding Squarespace using uncompressed JavaScript and CSS files.
Do you think this is a "real" issue and if so.....is it something I can fix?
Thanks
Damian
