Won't sync – Boxer For Gmail, Outlook, Exchange, Yahoo, Hotmail, IMAP and iCloud Email Review

Update: New update for iOS 10 compatibility . . . apparently not for email syncing compatibility. Really, really, really disappointing to have another great app ruined by a corporate developer. There is just no excuse for this kind of sloppiness from a company that has the resources to do better. Loved this app, but won't sync now. Support says "will be in next update" MONTHS and still waiting for an update. (Connects initially and downloads, but will only sync if account is deleted and re-installed.)
