Proof addition rules

[DanCl3]

If a designer adds a proof to a project, can another designer also add a proof to the project?  If yes, are there any exceptions? 

[VictoriaSellers]

Yes! Multiple people can add proofs to a project, given that they have the right accesses.

Thank you!

One follow up, can the 2nd designer replace the 1st proof if  the 1st proof is originated by someone else? 

[DanCl3]

Just checking in to see if this follow up changes you answer.
