Sorry for my bad english, but we have to talk english here.
Where is the option to make a BackUp for the messages? I cant find it anymore. i guess the developers delete it, because they cant make the app stable. Last time i need 3 hours to read my messages from 26.9.2016 to 8.9.2016, because i have to much messages (i use the app since start 2014 till today end 2016) and the app hang to much.
my old thread about the stable problem
