Thread Topology Monitor new version unavailable and old version incompatible with latestSDK

I am attempting to run the Thread topology monitor as per

https://infocenter.nordicsemi.com/index.jsp?topic=%2Fsdk_tz_v4.1.0%2Fthread_topology_monitor.html

1) First problem is the above refers to nRF_TTM-win32-x64_v0.13.0 and this is not available on the linked https://www.nordicsemi.com/Software-and-Tools/Development-Tools/nRF-Thread-topology-monitor/Download which only wants to offer https://www.nordicsemi.com/-/media/Software-and-other-downloads/Desktop-software/nRF-Thread-topology-monitor/nRFTTMwin32x6401201alpha.zip i.e. 0.12 alpha.

2) Second problem is that attempting to flash

nRF5_SDK_for_Thread_and_Zigbee_v4.1.0_32ce5f8\examples\thread\cli\ftd\usb\hex\nrf52840_xxaa_mbr_pca10059.hex

onto a PCA10059 Dongle using nRF Connect / Programmer fails:

Now it does seem to program things despite complaining. If I program the blinky example the LED makes exciting colours. If I put the CLI back you can open the serial port and talk to it. I note that unlike the blinky example the CLI firmware does NOT show a mbr coloured block in the programmer - it shows a solid green application section over both regions.

3)Assuming it's programmed correctly and attempting to use topology monitor 0.12 fails with a timeout:

4)If I find an old dongle that has the CLI programmed from last year all is well - but I've no idea what firmware that is.

Questions:

a)Can you provide a link to the 0.13 topology manager?

b)Is there a problem with the PCA10059 CLI hex file that causes it not to show a bootloader in the programmer?

c)Any other suggestions to make the topology monitor work?
