Yes, I did. I also got a post from my partner at 03:57:19 AM (UTC +7) this morning and didn't get notification.
But I just got one for this thread now so I don't know...maybe I'll try turning off and on the notify of all my threads.
If you got a notification for this thread, then you should get notifications for all threads you have notification on. So it might be better to wait an see than to go to all that trouble.
As for the PM notifications, I don't know. If you aren't getting them now, after reenabling them, then maybe only Veks can help you. Sorry
