Cortana: My W10 with 1709 stopped getting Android notifications

Problem:
After updating from Creators update > 1709 my Windows 10 Cortana stopped receiving defined notifications from my Android phone

My setup:
- Latest Windows 10 (1709) update
- One+5 Android phone with Cortana Assistant (with latest version 2.9.9)


Cortana is configured correctly on my phone (needed accesses granted) and user is the same Microsoft account than on my W10. On my W10 I have also defined/connected OnePlus ONEPLUS A5000 in Settings > Phone. On W10 Cortana, Manage notifications Mobile device is ON and I have selected a few notifications to receive (e.g. missed calls, low bat, a few app notifications). However NONE are coming to my Action Center on W10.

This worked like a charm PRIOR to 1709 update... Has this been temporarily disabled on W10 or ...? Any hints / tips?

And yes, I have un-installed and re-installed Cortana on my phone too.

Appreciated!

Pursued after this also on Microsoft forums...

Still no luck on getting any idea why the notifications have stopped and how to fix that (if possible). Tried so far:

- un-installed / re-installed Cortana for Android
- re-connected my account
- double-triple checked settings (both on Windows 10 & Cortana for Android)

Clueless...

Started to work again with Cortana version 2.9.12 on my 1+5 with Android 8.0. Must have been a sw glitch somewhere.
