Why can't I get the package advertisement in my mobile phone Tik Tok?

The first mobile phone network problem depends on whether your mobile phone has a signal and whether the network is connected. Second, there is something wrong with the memory of your mobile phone. It may be that your mobile phone is out of memory, so clean up the memory of your mobile phone at this time. Third, maybe your understanding of Tik Tok is too low. Please upgrade your version of Tik Tok. There may be something wrong with your settings.
