It comes down to who does the install. I am told they can definitely be finicky but generally speaking once in are good to go.
I’ve had ARBs in my old 3rd Gen 4Runner and 100-series, in my current 80-series and might get at least a rear locker...
It could be the spare chain. Easy way to rule it out would be to zip tie it.
Spitballing here:
Did you check the spare and make sure it isn’t moving around? I had that happen after a tire rotation at Discount. They didn’t have the bracket on...
I have the same phone with the latest updates and a 2018 LC. No issues for me. I actually think my BT connection has been better than it was in the past.
