EDIT: This app went from just good enough to do what I want to hot garbage dumpster fire. I can't even open the app without being forced to turn on "display over other app" because it's trying to force me to use the caller ID feature. Used to work really well now I keep getting an error when logging in to Facebook "For your account security, logging into Facebook from an embedded browser is disabled"

Hey Claudio! Sorry for the inconvenience. We've fixed the issue, so you can now enter the app without the "display over other apps" permission. Please update to the latest version. If the issue continues, contact us at support@sync.me. Thanks for your patience, and we'd appreciate a higher rating!🧡

So I subscribed and paid a monthly fee to see the report on certain contacts but for addresses it only tells you the country they are in which I already know. The report tells me there's 2 phone numbers but only shows me the one I already have. When I try to sync photos with my contact it tells me I have an Internet connection problem that I don't have. I have contacted customer support but don't expect much help due to other reviews. Potentially unsubscribing.

This used to be a great app and I have been using it for more than a year. Saved me a great deal of frustration with spam callers, let alone the caller ID feature. However, apart from making the calling experience slower by tapping the window away after or during a call, one sync at some point MESSED UP several of my contacts which now appear under different names (not similarly sounding) in the main calling app vs sms messages vs Viber vs WhatsApp. A complete MESS. Thank you Sync.Me!
