Just wanted to update this thread in that the following DID resolve my issue with my Yasnippet template which overrides the default "<s" template as I prefer "#+BEGIN_SRC" in CAPS instead of the newer lowercase variant:

#+BEGIN_SRC emacs-lisp
  (setq org-src-tab-acts-natively nil)
#+END_SRC

I include that section in my config, and it works as intended now :)

Thanks for the help on this, Org Mode rules like usual!

Yes, that should work. I have not tested it though.
