Hi experts

Anyone any idea how to resolve this strange problem.

The Ismart app on my android phone is not working anymore, no updates, GPS position or battery life or remote control for ac or heater is possible. It says car not responding. Latest version btw.

Strange thing is, i have Bluetooth connection with the app and the car in the app for Keyless lock and start. However nothing working.

I already rebooted the infotainment system. No Luck. Uninstalled the ismart app en reinstall. Login, same issue.

Installed on different android phone, login with account, same issue.

Then i tried to unbind and rebind it via the car. After rebinding and loggin in i get a error message on screen saying "invallid token" thats all. But the Login is succesfull however no Luck and app not updating nor working.

Anyone knows how to resolve this token error in car infotainment system/software ismart part?

Thanks for any help in advance 🙏
 
How is it today @breaky, i-Smart had been out of action for us all for a couple of days, but OK now.

Thread 'Anyone else having issues with the app today?'

The app hasn't been working at all for me today, I just get the below message. Anyone else had issues today?

@MG Clive Today the same issue, not responding and getting no updates. My region is Europe, the Netherlands.

Exactly the same as shown in the picture off that post 😀

Ok, during the summer of 2025 I had almost exactly the same issue as you describe. Except the message that I got was different. It said 'vehicle not responding' constantly. My dealer & myself tried everything to get it to work. Then MG got involved & tried to fix it after I contacted them through the app. It turned out I needed a completely new software suite to be loaded as a corruption to the Telematics system had occurred. This it appears was caused by a technician disconnecting the cars 12v battery when the car was still in the 'on ready state'. That's like shutting down your Windows computer by pulling out the power lead from it's socket! It caused some software corruption.

So after the car spent 3.5hrs on the MG server (paid for by MG) the problem was solved. Works every time now. Just food for thought.

That is exacly the same it says that in Dutch in the ismart app, "vehicle not responding, please try again later" this is since december 30th, but i checked in the cars infotainment system and when i open the user which is am logged in with it quickly throws an error message "token invallid" so that must be the issue. But i do not have any clue in how to resolve it in the car.

Our ZS EV is connected to our Home Assistant, home automation system, the integration "pretends" to be an "app user" so this works just like if you open up the app.

Here we have been without connection to the server, just like if we opened the app in these intervals since Januar 1

January 2. 12:36 PM to 10:08 PM
January 4. 9:15 AM to 1:40 PM

In Home assistant this manifests itself as "sensors" being "Unavailable"
 
Just got a reply from the ismart app support:
Guess i need to make a workshop appointment to get it fixed and sorted out, i have no idea what that box is :)

When that is done i will update this thread again !
Appointment made for thursday 15th of january, so a few more cold days of ice and snow scrathing from the cold car ;)

@MG Clive sounds like the exact same issue as you had!

Dear customer,

Thank you for your email.

It is recommended that you visit the authorized workshop to have the telematics box refresh.

Thank you for your cooperation and understanding. If you have any further questions, please feel free to reach out at any time.

Best regards,

ismart-service team
