Mathematica Online Share & edit functionality

Hi!
I have two questions:

1. If two ppl are viewing the document, and both have permission to edit, will the document be locked for editing to one of them?

2. If I edit the document will the changes happen in realtime for the other user (if we are watching/using the doc simultaneously)?

Thanks for answers!

  1. Yes, it is locked for editing by the first user who opens it.
  2. No, other readers won’t see updates in real-time, as of the current release anyway.
