If you use Swiftkey as your main keyboard of choice for all of your Android typing needs, you'll want to grab the most recent update to the application as the company has highlighted that the issue with sync errors which have been plaguing a decent number of users has apparently been fixed. For those that don't use Swiftkey, the third-party keyboard app for Android devices was having a problem which resulted in users receiving synced predictions that actually belonged to other users. Naturally this was causing some confusion along with what was likely a little bit of frustration and annoyance from the keyboard trying to offer up incorrect predictions. More so than anything else though, it was a cause for some users to worry about the privacy of their personal information.
Due to the nature of the problem, and likely the issues with privacy which resulted from it, Swiftkey suspended the cloud sync service back on August 1st until they were able to remedy the errors. While the lack of the cloud sync functionality no doubt was causing some inconvenience for users that relied on it quite often, it seems to have been a necessary evil in order for Swiftkey to not only fix the issue but ensure that no other users would be receiving the synced predictions that weren't theirs.
It is worth noting that while the cloud sync service errors have been fixed according to the update, Swiftkey has left the email and number predictions offline for the time being, with no mention of how long they'll remain in this state, unfortunately. Having said that, it's entirely possible that Swiftkey's next app update will re-introduce these features once again. In addition to the sync error fix, the update also introduces support for eight new languages, which includes Kurdish, Aragonese, Maltese, Nynorsk, Frisian, Luxembourgish, Faroese, and Asturian. A couple of other fixes are included in this update version n addition to the fix on the sync error, such as the fix for Samsung Galaxy S7 users which improves the typing experience on the device, as well as fixes for users that rely on the Accessibility and Talkback functions.
