Windows 10: How does one provide feedback to MS when one of the things that is broken ins the Feedback Hub?

Twice now, Sticky Notes have stopped working and lost all of my notes on two different PCs. When I tried to send feedback via the Feedback Hub, it will not accept anything that is typed in.

Feedback Hub broken: unending circling dots when I try to log feedback

I seem to have broken the Feedback Hub - I can't log any feedback ( I just get circling dots which never end).





This is on a PC where I've just clean-installed 1709 in the last few days. The problem happens on all accounts on the machine (one local, one local admin, one MS Account admin).

Other aspects of the Hub (eg. displaying news on latest Insider builds) seem to work OK, but I can't log anything.

So far I've tried

1. Going to the list of All Apps in Settings, selecting Advanced Options for the app and then Reset
2. Uninstalling the app using Powershell (using this Tutorial) and re-installing
3. Using the Store Apps Troubleshooter

Incidentally the thing I was trying to log was high CPU usage by Desktop Windows Manager - not sure if it could be related or indicative of another problem?

Any ideas on what I can try next?

Settings does offer this if you dig a bit from the Apps & Features list
