Isn't there another way of solving this? Instead of using WDRT?
My 640 updated to the mobile branch that broke away from the PC Creator's update and lo and behold, WhatsApp and the dozens of other apps started working again. All I needed to do was log back into the apps afterward since they had lost the login information.
So, the way to fix the third apps is to getting out from Creator's Update branch? Even I've already updated to Build 15208, it is still happened.
I'm running 15063.251 and it seems to be working fine except for that Edge problem with refreshing itself. The apps are working fine.
