Update keeps restarting?

Downloading the update in the background and checking occasionally and swore i saw it on 32/33gb downloaded then looks again 5 mins later expecting it to have finished and its back to 30/33gb downloaded?
I thought perhaps and misread it as 32/33gb but this subsequently happened 2 more times(at least) before I just shut the sodding thing down.
Try again at the weekend I suppose.

Lets hope I dont have to re-install the whole game again which has happened in the past.
Is this a windows store issue or is it unique to MSFS2020?
