Unable to access translated node content

After performing a Drupal core update on my site today I’ve found that I can no longer access translated content. When I try to view or edit the translation, I only see the default language content.

I created a short GIF you can view here:


As you can see, I’m editing the node for Canada and the US translation is showing instead. Translations were working fine with Drupal 8.6.2 but began to do this in 8.6.3. I have now done the following with no success:

  • Updated to the latest Drupal core 8.7.2
  • Updated all installed modules
  • Created a new Drupal site with 8.6.3 and 8.7.2, but this issue does not exist
  • Disabled Workbench moderation for a given content type, but that doesn’t fix the issue

I’m really not sure where and or how to troubleshoot this issue. Where would you start?

I’m thinking I could start by uninstalling modules to see which is possibly causing the issues. I’m not sure if that is the right approach given that this issue began when I updated the Drupal core, not the modules.

Thank you for any feedback!
