I saved an m file with %% for sectioning in R2020a.

Then, I opened it in R2021b, but %% didn't worked.

If I copy and paste the code in a new script in R2021b, %% works well.

I don't know what's the problem.

This is due to the invalid file name. Please remove the whitespace in the file name and reopen it.
