Hello,
1) I’ve changed the background color of Footer https://prnt.sc/1x8ditw , and it works fine even after closing the Customizer. There is no visible problem. Describe what exactly doesn’t work for you. 2) We’ve tested the speed of your site, it is not slow – https://prnt.sc/1x8dqko , but can be better.
