Grand Theft Auto 5 this week, both Rockstar Games Social Club and the GTA iFruit companion app have had numerous issues. According to an update on its support page, Rockstar is aware of problems like account linking being down, stats not syncing properly and content not loading correctly, and is working to resolve them.
While Social Club has been around for years, Rockstar just launched the iFruit companion app this week to coincide with GTA 5's release. The free app allows players to take care of Chop, the pet dog owned by one of the game's characters, as well as customize vehicles and license plates for use in the game.
Update: Rockstar updated its support page, noting it "made some changes that should help to resolve some of these issues, and will continue to work toward a full resolution for any remaining problems such as logging into iFruit."
