Pro subscriber who cancelled. The app had a conniption. It stopped syncing contacts, tells me various services are unsupported, and refused to actually answer calls Overall it has become more trouble than it is worth. this used to be a great app for me. It probably can be for someone else. I'm simply unwilling to spend additional time trying to make this work again. Based on what I've found it's down to some change Samsung made. Shocking.

I got annoyed with the app's interference in my call screens & logs a few months ago & uninstalled. Today I noticed a lot of my contact pictures are outdated or missing, so I figured I'd give it another try. When I went to sync with my Facebook friends, I got the same error message other reviewers have been mentioning: "Facebook is unsupported" - so there's no point of the app. Uninstalled! Again.

Mainly subscribed to the the app to sync with Facebook and Instagram. It worked for awhile, for what I wanted then one day the app logged me out, I could never log in again. I contacted support an they told me that an API changed and it would be temporary. I am not sure what that means??? So I just canceled my subscription and I am out the my I guess but at least I can warn others not to download.
