I'm sorry if I sounded that way, I didn't mean to.
I was just looking at the steps the OP had taken and the common point has been that he does a hard reset and hey Cortana disappears. If he doesn't do a hard reset but use a restore on 8.1, it causes system instability
So here's my idea, it may or may not work - I can't test this out since I don't have a phone at the moment
Go back to 8.1, don't restore. Just set up your phone like you would normally do - add MS account, let messages sync, let contacts sync - set up cortana. Don't set up start or settings
Upgrade to W10M official build, download critical apps, update apps, check that Hey Cortana works
Go to fast ring, download other apps, copy over data such as photos, music etc.
I hope that by the time you get to fast ring, there's no reason to do a hard reset
However, your point that MS needs to solve this is spot on and all I'm trying to do is give a measure of flexibility in options on what can be done. Depending on MS always to fix things will take longer
