Ever since Vzw rolled out 5G the app doesn't function like it should. App closes it's self regularly when trying to make a call, can be extremely slow switching to phone app from phone book or dialing from a Google search. Update- Did everything the reply to original rating suggested and the app is now slower and lost more function. I. E very slow to pull up number pad to enter at voice prompts & takes about a minute to reorient from portrait to landscape mode.
