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.
