The EF mobile app for iOS and Android is designed to work offline. To enable this, the app periodically syncs data and stores it locally on the phone. Syncing data requires balancing the need for the most up to date information as possible against a phone’s battery life. As a result, sync times differ depending on the type of data being synced.
The default sync times are as follows:
Attendees (1 hours)
Account Tags a.k.a. Interest Tags (1 hour)
Campaigns (1 hour)
Chatter (3 minutes)
Collateral (2 hours)
Conferences (1 hour)
Discover (6 hours)
Events (1 hour)
Exhibitors (1 hour)
Exhibitor Booths (12 hours)
Maps (1 hour)
Menu Items (12 hours)
Messages (15 minutes)
My Attendees (30 minutes)
My Events (30 minutes)
My Exhibitors (30 minutes)
Meetings (15 minutes)
Posters (1 hour)
Sponsorship levels (12 hours)
Surveys (1 hour)
Translations (12 hours)
Delete (15 minutes)
It is also possible to force sync data:
