So this is all I could find regarding an issue a friend of mine is having.
Fully stock Nexus 5 using GOSMS for messaging.
The messages show up in notification, but don't show up inside the SMS threads.
Eventually they appear, but not always.
Also their messages don't auto sort into the order they are received.
Re-installing didn't fix that, installing another sms app didn't sort it either.
Any suggestions short of doing a full wipe ?
