Facts
- I had created a top level folder in gdrive and moved all my folders into it. That way, I could share the entire top level folder with one particular person
- But I found that only some of the subfolders got shared
- No amount of googling found me this problem or any answer
- I finally decided to try just re-creating new subfolders and moving all the contents. Then I deleted the old, empty, and what-I-consider-to-be-corrupted folders. Easy Peasy
- Now all the subfolders are properly shared
