It's common to lose a few contacts when syncing from Breeze for a few reasons:
The contact doesn't have a valid mobile number.
It's a duplicate. Each subscriber must have a unique phone number. So if two contacts have the same number in a group (which is common in families), we will only sync one of them into Clearstream.
The number is not listed in the Mobile field. If a contact's number is listed in the Home or Work fields, it won't be synced to Clearstream, so be sure to copy it to the correct field.
If you need help figuring out why certain contacts aren't syncing, feel free to ask our support team. We're happy to help!
