It may be because your Douyin account has not been opened or bound to the relevant e-commerce platform, or the current Douyin homepage does not recommend products. You can try the following operations to solve this problem:

1. Confirm whether the account has opened the e-commerce function: Click "Me" in the lower right corner of the Douyin homepage to enter the personal page, then click the settings button in the upper right corner to enter the settings page, and check whether the e-commerce function has been opened in Account and Security.

2. Bind an e-commerce platform account: If you have already opened the e-commerce function, you can try to bind a related e-commerce platform account, such as Taobao, JD.com, etc. In the settings page, click "Account and Security", find the "E-commerce Account" option, and bind the relevant platform account.

3. Update the Douyin version: Make sure your Douyin version is the latest, sometimes the old version may have some problems.

4. Clear cache and data: Find the Douyin app in the phone settings, click to enter the app information, and then select Clear cache and data. Reopen Douyin to see if you can see the product.

If the above methods do not solve the problem, it is recommended to try uninstalling and reinstalling the TikTok app. If the problem persists, you can contact TikTok customer service for help.
