All we need is an easy explanation of the problem, so here it is.
We have a standard object (Quotes) with a custom lightning record page (flexipage) assigned at an org-level. I’m not sure what’s triggering it, but recently when we do deployments related to quotes, the org-level record page assignment keeps getting reset to the system default instead.
We have been setting this manually in each org (sandbox/production), but is there a piece of metadata that org level assignments get set at? I know there’s the CustomApplication option, where we assign it at an app level, which is our alternative, but if we can get it set at the org level and keep it, that’d be ideal.
