Answer 1

If you've tried some of the above answers and the problem still persists;

Ensure you are git "committing" in the right directory.

For instance, if your file structure is as follow:

/src
    /...
    manage.py
.gitignore
Pipfile/requirements.txt
Pipfile.lock
Procfile
runtime.txt

Ensure you're git adding, committing, pushing etc. from the root directory. Since we work mostly in the src/ or main_app_directory/ we tend to forget to change directory back to root before committing.
