Hi I did not get the stack error shown at the end of this video

@virancheeind Please let us know what stack error do you get exactly when you get a chance. Thank you!

The error is a result of trying to update the main thread from a background thread. If you didn’t get the error, then either you correctly updated the main thread, or you disabled that reporting. Feel free to post your code so we can review.

I watched this part like more than 20 times and I’m still confused

@george30 Do you still have issues with this?
