Apple has disabled Walkie-Talkie, its application for exchanging voice messages via Apple Watch, due to a security issue that could have allowed people to listen to each other's conversations on their iPhones. Apple has explained that it is not aware of any specific case of exploitation of the programming error, but as a precaution has not provided information on the problem itself or on how it could be exploited. On Apple Watches, the Walkie-Talkie app continues to exist, but if you try to use it it won't work – it will remain inactive until the company releases an update to fix the situation.
