I copied the staging app to production. The changes I made within a fragment (changing text inline decoration and removed inline link) have not been applied to frontend in production, although the changes are showing up within the fragment at the backend there. I had to change something within the editor (deleting a letter and adding it back) to make the editor recognizing changes, to save that, and all is fine
Update: It happened again, seems to be a general issue with fragments and changes within them, if webapps are copied after that changes (in my case just staging). Does not occur with template parts outside of fragments
