DOES NOT WORK!!!!!
I used the free trial to make a backup of my whatsapp on iPhone, which is technically possible according to Wondershare. After that I bought the full version so that I can also use the other functions. However, my paid version can not find the backup that I made in the free trial. In the meanwhile I deleted WhatsApp since I already had a backup I thought! Now I don’t even know how to retrieve the backup that is supposedly made out of the trial version and the full version can not find it either. This is very strange. Second problem; I then tried just to backup everything else I have from my old phone via the full version but it seems it can not find any data. This is very strange because the phone still has pictures, sms, notes, calendar, contacts etc. So, it looks like I paid for nothing!!!
