Utah politicians, civil servants, and medical doctors don't know anything about GPS or Bluetooth or Android or anything like that. What I bet happened was they signed a contract with a political crony and/or the lowest bidder and/or the one with the most women/minority/veteran/small business/HUBZone points, who developed this app and doesn't want to do any more work, at least until the state gives them more cash.
Meanwhile, the procurement office civil servants didn't understand the subject well enough to write in a provision in the contract to force the contractor to go back and fix it. When the press started asking questions, they went back to the vendor, they just gave a BS answer (which doesn't even capitalize Bluetooth), which both sides are sticking to in order to cover their asses.
Sounds like youve been looking at UK politics, because that's what's happened here. (Political crony/relative, literally and the price is beyond outrageous, as in order of magnitude )
First reports of the app are that it sucks battery as everyone technical said it would because it has to keep waking up to keep the BT system active.
Rumours are they are looking at pivoting to the A-G API.
I believe Australia is also in the same position and looking at changing API as well
