This problem is known. With ng serve the language can only be set via an url parameter. When the page should be reloaded, the language parameter has been disappeared and the default language is used again.

To avoid the problem a MULTI_CHANNEL configuration can be applied. With that it is possible to add the language information to the url path.

e.g.

MULTI_CHANNEL: |
        .+:
          - baseHref: /en
            channel: default
            lang: en_US

There is an open PR (#1447), which adds a 'preferredLocale' cookie, whenever the language is changed. This cookie is then considered everytime the PWA reloads. This will solve this issue too. But be aware that there are still some problems, why the PR is not yet merged.
