This is one of the suggestion we can find on Google to improve the Squarespace site speed.
How we can upgrade to 7.1 more easily?
Do we need to redesign the site with 7.1?
We can see some information here, since like there is a possibility to redesign or break the site if we switch to 7.1. Please advice.

Speed optimization suggestion:
1. Use Squarespace 7.1 rather than 7.0
I’ve found that in general, Squarespace 7.1 is faster than 7.0.
And, based on what Squarespace’s software engineers have been telling Squarespace designers in online forums, a lot of technical improvements are currently being made to Squarespace 7.1 to speed the platform up (with a view to ensuring that Squarespace sites eventually become compliant with Google’s new Core Web Vitals standards).
Importantly, Squarespace has announced that these improvements won’t be made to the older 7.0 templates.
