CAROLINABLUE, I have been struggling with this very problem. You click on Sync and it doesn't do anything.
BUT I found a solution!!
To Export your Contacts visit this link Export Contacts - Verizon Cloud - Website | Verizon Wireless.
I recommend saving the file as .VCF.
After you save the file, you need to send it to your phone. This can be done by multiple methods.
1) Email the file as an attachment to your self to download on your phone.
2) Upload the file to your Google Drive account and download it to your phone from there.
3) Plug your phone into your computer via usb and move the file into your Downloads folder in your phone file.
Once you have the VCF file on your phone, go to your Contacts on your phone and open the 3 dots on the right of the search bar.
Tap Import/Export.
Import from storage.
If it says Create contact under account, I don't think it matters which you choose.
It will say it's searching
Choose vCard file -> Import one vCard file -> OK
Choose the file you previously moved to your phone. If this is the first time you've done it, the file will most likely be selected already.
Press OK
and then you should get a message that your card has been successfully added! 
Hi MarkP – yes, the phone is on wifi. I can access the Verizon Cloud app from my phone and it is set so that it backs up photos and contacts every night. Every morning it says that it has backed up both “successfully” but the truth is that is has not. Only the photos are backed up -- the contacts are not back up at all.
The second problem happens when I go to the web Verizon Cloud...to manually put in contact information and then sync it to my device. It syncs and syncs... over and over... without stopping. I end up being timed out and the end result is that the changes done on the web do not get transferred to my phone contacts list.
In a nutshell:
- phone to cloud does not backup contacts.
- cloud to phone does not sync.
Side note, in case it is important: I am attaching an image of the Backup Assistant Plus where you can see that I am unable to tap "NEXT" as they ask me (the orange contacts image is blocking access). Thanks.
