Samsung GS3/GS5 Not compatible with Kit Kat. Messages do not restore. Only senders names. Please fix app./Dbl-checked app function to find it had stopped auto updating in Oct 2014. Manually prompted back up errors and stops  prompting error messages associated with IMAP settings  but my Gmail is configured correctly. Does not seem this app is receiving attention any longer. Is it just time to find a new one?
