My iPhone is connected to my 2.4GHz network, but I receive a 'Tip: please switch to wifi environment' message. Why?

The issue reported occurs when the permissions were not accepted during the app install.

  • You will need to uninstall and re-install the app, making sure to accept all the permissions requested.  

Changes in iOS 13 required app developers to request and obtain explicit permission to query network information, which requires access to the phone and location.
