The app that you are trying to use is "licensed" to the account that purchased it, ie: the old account.

You will have to download that app again under the new account in order to properly use it.

  • I already tried reinstall the app(I have login using new sandbox account).@ErniePC12 but it still did not work

Since iOS 12, the sandbox account are seperate management. In the setting-App Store-Sandbox account, you can manage and switch the sandbox account.
