In Touchdown, I could touch 'refresh' or a similar choice, and manually initiate a calendar sync to exchange, or a resync my contacts.
I didn't see that in Venus, and it didn't trigger an automatic sync after I installed.
How do I make this happen?
At the email list screen, pulling down from just below where it says "Inbox" should initiate a sync. You'll see the circle icon while in progress. This can also be done at the Contacts screen.
