LINE's Thai app update began rolling out from 1 September. The VOOM button on the main tab is replaced by OpenChat, and LINE VOOM closes at the end of September, so Story and birthday cards stop working too. Once you update, you can no longer open VOOM. If your business posts on VOOM or uses its Story or birthday cards for customers, move that content to OpenChat, your LINE Official Account or other channels before month-end.
