There is no prompt tone in the private message of Vivo mobile phone Tik Tok. Why?

It may be because you turned off the three switches as shown in the figure, so there is no message prompt when you receive someone else's private message. (as shown)

The solution is simple. Just open it. Let me demonstrate the specific operation method below, hoping to help you.

The specific steps are as follows: (demo version: Tik Tok 24.0.0)

1. After opening Tik Tok, click Me in the lower right corner.

2. Then click ≡ in the upper right corner and then click Settings.

3. Then click Notification Settings.

4. Then click on the private letter and make a phone call.

5. This interface pops up. Turn on the following three switches to receive private message prompts.
