Using a Flex 6400 with a Iphone 14 Pro on 5G while Mobile.

Like to ask this question to those that use a Flex 6400 remote with an iphone.
How many are using a Flex 6400 with an Iphone 14 Pro. With IOS version 26.0 and App version 7.0.85 on AT&T 5G service (Not WiFi) while mobile (Going down the highway) have any connectivity issues ? Audio or sound quality issues ? I keep my mic at 50% and my EQ levels all centered. Do you hold your phone and use the PTT with the mic\phone close to your mouth ? Do you use a head set ? Do you use the Apple ear pods ? Do you use bluetooth surround sound in your vehicle ?
The reason I am asking is some listeners to me on my Flex on a HF net reported that my audio was high or did not sound clear etc. So I am wondering if there is a way to actualy test this ? Of course I should probably start off in a fixed location on WiFi then move to a fixed location on 5G then go mobile on 5G and compare the three.
But my number one reason buying a Flex 6400 in May 2023 was to be able to use it remotely. That was my number one reason for buying this radio.
Thank you.
