Tile App on Key2

I am using the Tile app on my Key2. According to Tile, you are supposed to be able to press the button on the tile, and have the phone ring. I have pressed the tiles and it did not work. If anyone has been able to get this feature to work, please tell me what steps I am missing.

Thanks to anyone who can help.

Works. on my key2. just tested. does not ring as in phone call but rather the default tile ring. did you activate the find my phone toggle in the Tile setup? Also, are notifications on for the Tile app?
