Sorry actual WhatsApp no issue at all I can see my files and pics and even I can see seperate folder called "WhatsApp" inside gallery where I can see all of my original WhatsApp files
But problem is I can't see my dual app WhatsApp files in gallery or I can't see that dedicated folder called "Dual app--->WhatsApp"
I don't think it's WhatsApp issue
This seems to be an issue with the latest update from Whats App.
Your patience is appreciated while a solution is found.
In the meantime, try restarting the device.
thanks in advance.
