UPDATE: MessageMe co-founder Arjun Sethi told Mashable that the company will have more updates on Tuesday morning.
“We’re currently working to make sure our users don’t encounter any errors in the application when using it.”
Users of the free iOS and Android app, which offers group and individual messaging, can no longer search for friends using the social network, TechCrunch reported Friday.
The incident is another example of Facebook’s stringency around access to its social graph. In January, it shut off friend-finding access to Vine, Twitter’s new video-sharing app.
