I'm from South Africa and I'm seeing only local content in my feed. I've tried everything I can think of with regards to app settings but I can't seem to get any international content. Previously I was getting international content but after I updated Tiktok over a month ago, it's been like this.
You might need to change the language of your TikTok since TikTok won't send you videos that are outside the language(s) you select in the app. You could probably check and try this steps
Open the app and tap on 'Me' (lower right corner).
Hit the 3 little dot menu icon (upper right corner).
Tap 'Content Preferences' in the Account section.
Add the language of the region you want to see videos from
