Thank you!

I edit my .tex in local with auctex but then share it on overleaf with other people for collaborative editing.
\RenewCommandCopy is required on overleaf to avoid a warning and that is why I would like to keep it.

Would you know how I could update my LaTex kernel?

Sorry, here is my .log file.
Thank you!

Hello,

To avoid conflict between siunitx and physics packages, I followed the recommendation and therefore used the command :
\RenewCommandCopy{\qty}{\SI}

Everything works fine on overleaf but my auctex version (13.2.1) raises an "Undefined control sequence" error associated to this command.

Here ...
