Your explanation is very interesting, I’m also on version 7.0 – Bedford Family (Bedford template) and I have the same problem with the maximum number of enabled pages allowed, 20 pages.
We want to understand if when you say "you will lose all code injection, except for custom CSS and certain code in code blocks" you are referring to code entries that we could have expressly introduced or if we would lose codes that are included by default in the Squarespace template.
Thank you, we look forward to your reply.
