Rockstar has acknowledged issues with its Social Club and the recently released Grand Theft Auto 5 iFruit app.
Users have reported problems in connecting the Social Club and logging in to iFruit, which Rockstar has said it is working to resolve quickly.
"We are aware of these issues with Social Club or related networking hardware/services and have been working to resolve them as quickly as possible," Rockstar said in a post on its games support page.
"Please note that we are aware of some reports about problems with the iFruit App (available on iTunes), such as login errors, endless loading spinners, and the app appearing to reset data. Rest assured that we are working to resolve this as quickly as possible."
The iFruit app became available shortly before the release of GTA 5 and allows users to customise their cars, create license plates for GTA 5's story campaign and GTA Online, as well as teach Chop the dog new tricks.
CVG's GTA 5 review describes the crime-opus as "sprawling, thrilling and beautiful", declaring it "the best Grand Theft Auto yet".
