Hello everyone.
My micro:bit simulator has not been working well for some weeks now. And my students have also been experiencing that.
Whenever you run a new program, the old program which had already run on it will show up.
I have restarted and even shut the App down and switched it back on. But the same thing happens.
Sometimes the program being tested in the simulator doesn’t run at all.

Do you find that the same thing is happening in Beta?

I would have to try using Beta (using the link you have posted) and give you feedback

I just want to make sure I understand:
1. Can you confirm: The simulator code area shows new code, but the actual behavior of the simulated micro:bit is unchanged. Is that right?
2. What happens when you download/program the micro:bit? Does the behavior shown in the simulator change? Does the micro:bit behave like the old code or the new code that’s shown in the simulator?
3. Can you share links to some example programs that don’t seem to run? (Instructions to create a share link are here: [https://makecode.microbit.org/share](https://makecode.microbit.org/share)).
