Share OmniPlan 3 plan with Older IOS OmniPlan

We have a client that has OmniPlan Pro 2.5.2 on his iPad, we are using OP v3.4.1 Mac. Is there any way we can share the plan for his project with him? He doesn’t need to write or go both ways, just read the OP document.

If you both have Pro, you can use the Multi-User Publication and Subscription feature to sync the project. Without Pro you could use OmniPresence Sync. More information on both are available in this support article.
