Apple continues to iron out bugs in its, acknowledging a problem with iMessage, which it plans to fix in a forthcoming update.
The update should resolve an issue affecting iOS 7 devices that's been causing messages sent over iMessage to fail. iMessage kicks in as an alternative to SMS when there's a wi-fi connection available; however, users began piling onto message boards from 29 September to share complaints about outgoing messages not sending.
Apple's UK system status dashboard does not indicate problems with any Apple services over the past several days, except a one-hour period of "delays or slowness" on iMessage on 30 September affecting 10 percent of users.
To fix the problem on iOS 7 devices, some users have suggested a turning off iMessage, resetting network settings, and then re-enabling iMessage.
Acknowledging the issue, Apple earlier today pointed uses to its troubleshooting documents while it prepares a fix.
"We are aware of an issue that affects a fraction of a percent of our iMessage users, and we will have a fix available in an upcoming software update," Apple said in a statement to the Wall Street Journal.
"In the meantime, we encourage any users having problems to reference our troubleshooting documents or contact AppleCare to help resolve their issue. We apologise for any inconvenience this causes impacted users."
The fix may come with the release of iOS 7.0.3, which supercedes iOS 7.0.1 on iPhone 5c and 5s devices and iOS 7.0.2 on older models. The update is reportedly being tested internally at Apple for an expected release next week.
ZDNet has contacted Apple for further comment and will update the story if any is forthcoming.
