We have a custom post type called "case studies", and the slug for it is translated via string translation.
Straight after resaving permalinks, it works well. If we edit one of the case studies (not even a content change, just going to the edit screen and clicking update is enough to break the permalinks). The symptom is that the translated slugs don't work and return a 404.
The desired URL structure is as follows - these are just some examples to show that the term case-studies in the URL should be translated for each language/locale:
Sorry for the delay in this - I'll be doing some testing today. A fix for another issue we face could also be the fix for this. Once I've done that bugfix, I'll test this again.
Sure! Please test according to the instructions shared by my colleague Drazen. Additionally, ensure that each post type in every language has a distinct slug. As per the guidelines by WordPress, slugs cannot be identical as it can lead to unusual issues on site.
