Hi DARLINGTON ETAJE,
We are investigating the sources for the cause of not saving new code and even some times the save may be delayed especially for large files
The reasons may be
- If the app is large then tab completion in large files can delay the save
- Parsing the contents of the file to fill in App Designer's Code Browser
The team is investigating other sources as it appears there are more causes for this than just the two above and may be fixed in future releases
I recommend splitting out some logic from the main MLAPP into external M-files to reduce the size of the app.
