@zhouxin627 I tested this about 10 times on iOS 13.3.1, sdl_ios v.6.5.0 (Swift example app), and a Ford Sync Gen 3.0 (build 19205_DEVTEST) TDK 12 times and encountered no failures. Could you attempt this with an iOS 13.3.1 phone and sdl_ios v6.5.0? Otherwise, I wonder if the issue is related to your HMI / iAP connection.

[zhouxin627]

@joeljfischer Thank you for your response. I will test it with sdl_ios v6.5.0 and inform you of the result as soon as possible.

Hello @zhouxin627, do you have any additional information?

[zhouxin627]

Hi @joeljfischer, we have tested it with an iOS 13.3 phone and sdl_ios v6.5.0 in our environment, but still encountered this problem. Now we are doing further research to give you more details. Could you please give me some more time with this?

[joeljfischer]

Certainly! I just wanted to check in since it had been a few weeks.
