Share Google Contacts with Shared Contacts®

I normally have no problem paying for services I truly value. Unfortunately, Shared Contacts (now rebranded as Contacts Flow) is one of the worst products I have ever paid for. The service is extremely buggy and unreliable, and the customer support is poor. This time, the most disturbing issue is the contact synchronization itself. People I have never seen or interacted with suddenly appear in my contact list. At one point, dozens of contacts with Korean names were mixed into my existing contacts. In another case, I discovered that my sister's profile photo was attached to a contact named "Steve Staunton" - someone I do not know. This is not a minor glitch. It indicates serious synchronization failures and raises major privacy and security concerns. A contacts management service that randomly merges identities, photos, and personal data simply cannot be trusted. On top of that, there is a real risk of data loss. Contacts can be overwritten, corrupted, or deleted without warning. When you combine this with severe security issues and ineffective customer support, the result is a product that is unsafe and unusable. I strongly recommend avoiding this service if you care about the integrity, privacy, and reliability of your contacts.

Lack of response from Support gets them 1 Star for this application. I have zero tolerance for unresponsive personnel. I have been trying for months to get these folks to correct their invoices which do not match what is actually being billed. They do not respond to any support requests at all.

Doesn't seem to work anymore. I sent a support request to the issue I was having and received no reply. I also checked the support tab on this page, and saw that other people were having the same exact problem, but there was no reply from the developer. That issue is regarding Authorization Error 400. I was ready to pay for this. Instead I will delete it and look for something else that works.

At no point was it made clear this is a paid add on. I had to complete the set up process prior to learning this would require multiple licenses. I will not deal with a company that blatantly obfuscates their intentions.

Messed up my contacts, now I can't access them.

When contacts are deleted they reappear resulting in people getting emails who do not want them. This makes the service essentially useless.

We've used this for years. I like what it does and it is fairly easy to administer but recently, it has caused us a lot of problems. It drops contacts off of lists. We put them back, and they randomly drop again- the contacts are there, but the labels are empty. They randomly cancel our subscription, and we have to scramble to tell them we did not cancel, please fix. They'll fix, first saying our credit card was wrong, and then admitting it was cancelled on their end. This happens to our account 1-3 times per year. Then they come out with this extension, which looks great, but they forgot to mention it doesn't work with our version. We have to remove the app from the apps grid and pay for a more expensive version to receive the same product tomorrow that we have today. I don't know why they are having all these technical problems, but it causes us as admins a lot of work to monitor this app all the time. It should just work without us constantly asking them to fix problems that seem to be caused on their end.
