If a proof has more than one version, you will be able to compare versions.
To compare proof versions
Step 1
Open the proof and click the compare icon at the bottom of the screen. This icon will appear if the proof has more than one version.
Step 2
The proof versions will display side-by-side. If the dimensions match exactly, smart compare is available. Comments can be added in compare mode too if the proof is in a status that allows commenting.
Tip: You can also compare two different proofs.
