Sangoma Connect Refresh Address Book

In the sangoma connect app I’m trying to figure out a way to refresh the business address book. On the android app I can go into the contacts and pull down on the contact section and I get a message that says “business contacts synchronization is in process”.

However on an iPhone I can’t seem to find any way to perform an address book sync. If I do the same thing and go into the contacts and pull down the contact section, I don’t get any sort of notification that a sync is in progress (like I do on android). After performing that function and checking the address book it still isn’t up to date. Anyone with an iPhone know how to perform an address book update?
