I am glad to report that since 2015-Dec finally my 950XL under latest update 10.0.14393.448 works very very nicely with all notifications wake up in mornings after Quiet Hours. [Before this update notifications & reminders usually continued sleeping after Quiet Hours ended]. Now I can claim I have a RELIABLE MS Lumia 950XL 2SIM cell phone. Many thanks to all the folks for their commendable efforts in updating related software & apps. :excited::grin:
