Button on app  to activate list device protection does not work on iPhone 13

It doesn’t work on my iPad Air why?

Hi @shaunee8,

How were you able to tell that the feature is not working? Have you enabled all app permissions? You may follow the steps on the article provided below to allow the said permissions.

Cannot turn ON Lost Device Protection on iPhone or iPad

Also, could you provide the application version of your Trend Micro Mobile Security app?

Thank you!
