The latest Handheld Contact build for IOS has just been approved by Apple. The build is 7.3, and addresses a number of calendar issues with 7.2, and a number of sync issues with 7.1.
Two points on IOS11 that we want to make.
For those that switched to "HHC Legacy" during the past few weeks, we want to remind you there is no upgrade path from Legacy to HHC 7.3, as the latter is a different product from Apple's perspective. Those users will have to uninstall HHC 7.1.2 from their device, install 7.3, and then do a resend-all from their HHC computer software (please remember not to let your device time-out during the initial sync).
