HiCould you please try out the following?a) Please check if mbox.js is
present in the website. If present, make sure
"includeExperienceManagerPlugin" is set to true. If false, target
libraries will not load in VEC.b) Check for target libraries while
opening the website in the VEC. Go to the browser network window and
check for the presence of target.js.If it continues to fail, please also
share the site URL.
