When ReviewX ships new strings in an update, your existing translation file doesn’t automatically pick them up — you need to sync it once so Loco Translate knows about the new text.
Step 1: Open your existing translation
Go to Loco Translate → ReviewX and open the language file you’ve already translated.
Step 2: Sync new strings
Click Sync — Loco Translate compares the current plugin text against your file and adds any new, untranslated strings.
Step 3: Translate and save
Fill in translations for the newly added strings, then click Save. Your file now covers everything, old and new.
