As mentioned in comments, --lab is deprecated. But --prod should work.

If you are using it like this:ionic build -—prod; npx cap copy ;, then it won't have any effect. because npx cap copy builds the project first and override your previous build. you should use it like this:

npx cap copy --prod

npx cap sync has the same situation. they both build the project first. and if it works like this somewhere else, there might be a versioning problem.

However, if these are not your case, please specify what is your expected behaviour and how is it failing to achieve that.
