"Your Phone" won't connect to phone after motherboard replacement

I've had the Your Phone app running for the last few months on my Windows 10 Pro PC, connecting to my LG V20 phone (Android v8). Last week my motherboard failed, so I replaced it and restored my Windows setup to a new SSD while I was at it.
Now the Your Phone app won't connect to my phone - it says: "We can't connect to your phone. Make sure that your PC and phone are connected to the internet".
The name of my phone (V20) is still displayed in the top left corner of the app Window. Both PC and phone are connected to the internet (via the same router). I have tried:
- Uninstalling and re-installing the Android app (and re-adding the necessary app permissions)
- Resetting the Your Phone PC app
The Android app says "Check your PC", and tells me to select "Send notification", but that option isn't available anywhere in the PC app that I can see.
Can anyone advise on how I can get re-connected to my phone?

...one step forward...one step back...after another re-installation of the Android app I was able to get as far as sending a notification from the PC app, and selected "Allow" when the notification came up on the phone. Now the phone says "Your phone and PC are linked", but the PC app still says "We can't connect to your phone"

Your Phone app not working

Perhaps this may be of help clearing up some confusion.

If you do a search for "Your Phone" via the Windows 10 start menu, the result takes you to the "Your Phone" app page, which gives you the options to connect/sync your computer to your phone. It is the settings on that page that I have struggled with, because they lead you nowhere, with no way to complete the process. At least, that is my experience.

But there is another choice in that also shows up farther down in the start menu "Your Phone" the search results called "Link your phone". It takes you to a different settings page titled "Your Phone", but gives you options not found on the Your Phone "app" page, including the ability to add a device, and most importantly, "unlink" your phone. This is the crucial step, which will lead you to the next step of re-linking your phone on your computer. You will come across a popup that displays a QR code (you will be asked to scan this QR code in a further step), and you will be asked to install the the Your Phone app on your phone (even if it is already installed), upon which it will then offer you to confirm the process by either scanning the QR code, or signing into Microsoft.

For me, for whatever reason, scanning the QR code did not work, but signing into Microsoft did complete the process.
