A small number of users report problems with Apple Wallet because the Apple Watch version does not sync properly with the iPhone after the latest updates (iOS 15.3 & watchOS 8.4).
Apple released a number of updates a few days ago, including iOS 15.3 and watchOS 8.4. Although the updates were mostly bug fixes, a new problem seems to have arisen in a few cases. For a few users, updating their iPhone and Apple Watch to the latest operating system versions results in the watchOS version of the Wallet app only occasionally syncing with the iPhone Wallet. According to a Reddit post Cards and passes added to or removed from the iPhone Wallet are not transferred correctly to the Apple Watch Wallet.
iOS 15.3 & watchOS 8.4: Number of complaints is low
However, the comments indicate that the problem only occurs when trying to sync the iPhone Wallet with the Apple Watch Wallet. Removing cards and passes on the Apple Watch also removes the same cards from the iPhone Wallet. The relatively low number of complaints, at least so far, suggests that this is not a very widespread problem. It remains to be seen whether reports of this will increase. Users who have contacted Apple Support say that the problem is being investigated, but that a solution is not in sight. (Photo by Unsplash / Cezar Sampaio)
