I got logged in about 4 times, each time I responded to the page displayed, lost connection, then when I reconnected again, I would be a stage further down the process and then eventually made my payment. So basically, even if you lose connection, the cogs are still working to what you last submitted.
But, my LEL homolumigation ( I know its spelt wrong, brain fog from catching covid) number would not work and still does not show up in the results page as it was supposed to do so we was informed in another posting, luckily I had a "1000" from earlier in the year.
Confirmation Email for payment received,
So I am in, 18:15, same time as my two earlier PBP's so I don't have to replan my timings so much, and will be my 3rd and last time.
