I've been using Disa on a dual sim phone, allowing whatsapp on the other number, for over a year with no problems. Now an error message appears that I need to re my name, phone number and codes. When I do so my phone number isn't recognised. I got Disa to start again by uninstalling and reinstalling without the second sim in. But now when ever I try to recover previous data from Disa (from the SD card) Disa fails again. I can't see any of my previous conversations, OR if I recover them, Disa stops. Any help?
