Only other thing I sometimes see mentioned is "removing" the USB instead of re formatting it, but reformatting it will ensure it doesnt have data on it so frankly shouldnt make any difference.
These things normally resolve when the car fully sleeps, but using the power off command and letting it sit for a while without checking the app (and without anything else preventing it from sleeping, like sentry mode, etc etc) usually will resolve it.
If not, you likely need to open a service appointment (after verifying that when you powered off, you let the car go to sleep and there wasnt anything keeping it awake, like sentry mode).
