I've seen dozens of people reporting the backup issue on the community (i. e. one changes or resets his phone and all backup data cannot be restored or synced, despite being seen on the account, simply one has to start from zero). Now I'm having the same problem. I couldn't find a single answer or solution from SwiftKey customer service. I contacted them and no response. It's very frustrating. Does anybody know a solution? Or something I don't know? Why are these guys not fixing this huge problem?! The app is totally worthless without a backup!
