Microsoft MakeCode

Github mystery - ALL JOBS HAVE FAILED

Hi

I have some code that every time i push the “Commit & push changes” button seems to work fine but about a minute later i get an email stating ALL JOBS HAVE FAILED

if i then click on the link in the email i am taken to Github page that tells me the program is too large by 2200 bytes!

However i can still access the code & upload it to my Micro:bit

Is this a problem with my code or something in the MakeCode system?

Please advise as i have never had this before

Regards

jason
