Hi @Max, I’m also facing the same issue even with the specific post URL, it still shows no post to display.
Please advice. Thank you.
Hi there and welcome to the Community, @Hello_Watchskins 
The thing is that our app pulls in only 30 most recent posts from the TikTok profile. Since the added videos aren’t included in 30 latest posts, unfortunately, it’s impossible to display them in the widget. I am sorry 
If you have any questions left, feel free to let me know. I’ll be delighted to help!
