if you are on the tik tok website on safari, you are able to view a video that originally brought you to the website the from the search log, but if you want to click on another video listed on the website, it claims you need to use the app to go farther, and upon proceeding it just brings you to the App Store regardless if you have the app already or not , and you are unable to view the video displayed on the website without searching for it separately on the app.
