Why can I no longer sign into my Contacts+ account?
In an effort to increase enhanced security for our apps, we've stepped up our game and made some improvements. To benefit from these changes and continue using our apps, we kindly ask you to update to the newest version of Contacts+:
Contacts+ for iOS and Contacts+ for Mac:
Open App Store → Updates → Contacts+ → Update
Contacts+ for Android:
Open Play Store → ☰ → My apps & games → Updates → Contacts+ → Update
You'll achieve the same by simply deleting / reinstalling Contacts+.
