Why Tracker App doesn't use SMS messages?

Quick answer:

Tracker Hunter 6 does not have permission to process text messages (SMS) directly, as added restrictions to security settings by Google no longer allow third-party applications to receive / send text messages

As a result, previously used SMS tracking is no longer available

On Apple iOS devices, the use of SMS messages has never been possible with the Tracker app
