According to LINE, a lot of these Broadcast Messages have a 55% open up level in order that they're successful instruments to market your brand name, products and solutions, and companies. 為何要做個簡單修改卻沒辦法存檔，加入好友的自動回覆部分，修改完所需要內容，都存檔了卻返回一直告知尚未完成部分將刪除，按了存檔依然沒有，所以編輯都沒辦法存檔變更，能不能處理一下，整個系統也太多bug了吧... https://elliottrunlh.webdesign96.com/36464519/line-business-id-options
