在Instagram页面加入下载按钮与开启按钮，透过这些按钮可以下载或开启大头贴与贴文、限时动态、Highlight中的照片或影片
Update: The problem with videos reported above has disappeared by yourself, now everything works.
Update 2: Downloading from the person profile works but for the first story you need to advance to the second story and return to the first story again, if you try to download the first story without advancing the download will show an error "unkown_date_hour_.mp4/jpg"
If the person only has one story, the download will not work on the person profile, you will have to download it from the home page. This problem does not occur on the home page, everything works fine there.
With the 1.17.16 update, video downloads in person story now starts but show an download error, unkown_xxxxxxxx(date)_xxxxxx(hour)_.mp4
For photos it appears to be working well
Thanks for the update and your time.
