I have project that compiles and runs on the Mbed board, but I cannot export from the online compiler. I tried many of the export toolchain options listed with no success. I get the same message “Failed to export.” I am running Windows 10 on Chrome browser. I have some of my old personal Mbed projects (2012-2013) on the online compiler and they compile and export successfully.
In the upper right corner of the online compiler, while in the browser, I see the numbers 1.10.25.0.
