Connection issue with infotainment

Hello, my partner has a 2023 Yaris Cross with the TAS600 infotainment system. We have noticed that it regularly looses connection with our phones when both wireless and wired. This never occurs in my own 2024 C-HR.  The car has been brought back to our Toyota dealer, but they can't find anything wrong with the infotainment system. 

Has anyone else had similar issues or any advice to rectify the issue?  Thanks for any help. 

Are both phones linked to the car?
Are both phones in the car at the same time when this happens?

No, when they are connected at different times. Depends on who is driving.

my wife has a 2023 cross not sure which system she has but its the bigger screen as she got the tech pack. Hers will often not find the phone over wireless when starting the car so she has to connect manually using the infotainment system. We have put this down to the android bug rightly or wrongly as hers is a Samsung phone. There is also another bug about it looses connection if it looses mobile signal. But not sure either of these bugs will be effecting you and I think they are related to only wireless connection so would not explain why it would do it on cable.

Perhaps just double check the infotainment software is up to date

YC Excel, 2023 model, Pixel 7 phone, always use USB connection for phone. Occasionally - about 1 in every 20 journeys - if I'm using Android Auto the infotainment screen will suddenly dump me back to the home screen. Pressing the Android Auto button then does nothing, need to remove/replace USB lead, instant reconnection. Only seems to do this on long journeys, not noticed any correlation with signal strength etc

Thank you all for your help
