hmm... is this related to the priority of rich menu...? https://developers.line.biz/en/reference/messaging-api/#set-default-rich-menu document says rich menu is set by the following order. if you applied per-user rich menu, you can't set defaut rich menu even if you apply new default rich menu.

  1. The per-user rich menu set with the Messaging API
  2. The default rich menu set with the Messaging API
  3. The default rich menu set with LINE Official Account Manager
