On both Mac O/S and Ubuntu changes to my views do not seem to be detected when either using --dev=all or --dev=xml. However python changes are detected. Any suggestions on how to debug? 

I did have this issue on Mac OS originally and then it seemed to 'just start working'. However, today it won't work on Mac and in desperation I tried the same with a new install of Ubuntu (Elementary OS 6) and the same issue. I'm all googled out :)

Any help gratefully welcomed.
