My Volvo App mis-behaving (2020 V90)
 

Despite my car being locked my app says unlocked. I unlock the car and lock successfully with the app. However, the app says it failed to lock the car and still shows it as unlocked.

Any ideas anyone?

Try starting the car and turning off and locking it and log out of the app and log back in, if that does not work delete the app and reinstall it,
Sometime rebooting your phone sorts out odd behaviour.

I know this might sound facile, but turn off your phone and turn it on again. Then try it.

Same thing happened to me and it was the last thing I did, before removing the app and downloading again.

Many thanks for the advice!

I went to start the car and heard a ping which was telling me something. I then remembered that I had opened the bonnet earlier and forgot to shut it.
User error I'm afraid!!! (again)
