DWP

Hello all respectable people. I am DW pro user since last 3 years. My call logs are really important and required by me all the time. I changed many phones and my logs were transferred to all of my phones easily. But I observed that logs were missing from last three months of 2017. Those logs are really important and are needed by me. Can you please tell me way to recover those lost logs of three months? Is this feature available? why did this actually happen?
I will be very thankful to you if you if you please figure out any solution for me!!

Hello there
If you have to do a backup in the backup manager. You can try to revert to the previous backup. Make a backup of the current state before doing it.
