Translation json files will not update in Frontend

Hello guys. There is some complicated translations to be done, espacially with placeholders and I would like to test them before I submit them in lokalise (and wait for it to be pushed with HA update).

Long story short, I have root access to my test environment and I can access translation files within /var/lib/docker/overlay2/... /hass_frontend/static/translations/ folder.
I have changed my language json file, I also updated “same” file inside .gz language file. I cleaned browser cache, changed UI language, restarted HA and even host, but translation from *.json file will not update in frontend. What am I doing wrong?
HA supervised on Debian inside VBox. Anybody can help, please?

Too bad nobody answered. I’m seeing the same thing while modifying an integration. Editing the strings and translations/en.json files & restarting does not change what you see in Configure options.

I just had an ah-ha moment and did a shift-reload page in Edge and that fixed it!
