# E15020 — WhatsAppTemplateLanguageNotEditable

This language is under review at WhatsApp and cannot be changed until the review finishes.

- **HTTP status**: `422`
- **Type**: `validation_error`
- **Name**: `WhatsAppTemplateLanguageNotEditable`

## What to do

WhatsApp is reviewing the copy you last submitted for this language, and it accepts no further change until it answers. Wait for the verdict — approval or rejection arrives on the template, usually within minutes — then edit the language and submit again. Reloading the template does not clear this; only the verdict does. Languages that are not under review can still be edited and submitted in the meantime.
