Oh, nice! I knew it must have been related with some condition being met because it works for empty lists (then storing new data), but doesn’t work for full lists (then storing new data) as it converts everything to dictionaries as if I am using no lists at all.
Thank you. I wasn’t sure if it was App Inventor source code or Kodular.
I looked at the problem on github. It says that it is already merged and code was changed back in February/March of this year. Does merged mean the problem was closed/solved?
