Hello!

With some of the larger libraries we get the warning that it will only fit onto the micro:bit V2. This is no issue as all our microbits are V2 version. The problem is that this message seems to pop up each time a download is executed after the USB cable has been reconnected. We mostly work with driving robots and each redownload needs the cable to be plugged in again and the message needs to be confirmed. Not a big issue but a bit annoying…

Is there a way to the the project that a V2 is used to supress this message?

Thanks,  
Michael

I think this happen right after you plugged in the microbit and makecode does not know which type of Microbit is connected. When you wait after connecting (via webUSB) the warning does not appear anymore
