I installed https://play.google.com/store/apps/details?id=com.olo.dairyqueen.production recently, and it hangs when attempting to use location services.
I tried turning off "Use precise location", the app asked me to turn it back on but I declined, and now the app works. Insofar as I haven't made an order yet, so lacking precise location might still be a problem.
I've raised this with Dairy Queen.
