So, reading documentation regarding locker-service I get that the only way of disable it, is downgrading the api version of each component to 39 or less. Also, documentation says that there is no hierarchy between components regarding locker-service. That works fine in one org that I have, but in another org, it's not working as expected. Could be some other reason for that? Some extra configuration that i'm missing?
I have two scripts that are loading form a static resource (with public cache) in one component, I downgrade that component to version 39 so those scripts are not loaded with data-locker-src, in a sandbox org works fine, but in another sandbox org this does not work, it still load the scripts with data-locker-src.
I test the site in an Internet Explorer 11 and as documentation says, locker-service is deactivated (tested with the problematic org)
