I generalized because that's 80% of what I read (a rather overwhelming majority) - Now, I realize that this thread was to report problems, but ...
You know what will fix your problem, but ' ... it's a time consuming procedure.'. I gotta ask, what prep did you do before installing the update ?
In my case, I moved ALL my apps back to the phone, took a good backup, removed the SDcard, hard reset the phone, let the restore happen, took the update & let it do it's thing (restore again). The prep (move apps & backup) took some time, but I was ready to install a clean update (and avoid potential problems).
A matter of '...you can pay me now, or pay me later ...' - plus I shutdown once a week, to allow the memory (RAM) to heal itself it makes RAM contiguous, leading to better performance. Point (don't repent later, do something in prep) was lost on you (& most) I imagine ... and, I will say the issues you mentioned were the most plausible examples of what this thread was intended for. The 'I can't get Cortana's' in Bengladesh (or somewhere Cortana has NOT been deployed) just drive me batty !
If people want help, they need to provide enough info to make an informed guess to rectify their problem. How many people have their passport info filled out on this forum. That would be valuable info (it's only a one time thing) towards troubleshooting. Where you are, what device(s), etc.
... and it appears, YOU stopped reading my post after whiners. There was a bit more substance.
Read the post, right after you called me out ...
