If you're confused or having issues with your Contacts merging, please see below:
1. Multi source
EasilyDo only merges contacts that are within the same group or source. What this means is that EasilyDo will never merge contacts for a name that exists in your Gmail contacts and also in your Exchange contacts. The app will not offer to merge these so that you can maintain your separate contact lists.
2. Linked contact
EasilyDo will also not merge ‘Linked Contacts’ with any other contacts. You can check if your Contacts are ‘Linked’ by tapping the iPhone’s Contacts app -->Select a Contact -->Scroll to the bottom to see if they are listed as a Linked Contact.
3. How to restore
From the Cards page, you can restore any contacts EasilyDo merged together and restore them to their original settings. Tap Contact Management>Merge Duplicate Contacts>Restore Contacts option. From there, tap the name of the person whose contacts you’d like to restore their original state and EasilyDo will separate the contacts for you.
