Can't Sign Into My SpeedTest.net Account

I have a SpeedTest.net account, where I've been accumulating test results for a number of years. Neither of the Windows 10 apps (the desktop app or this UWP app) will allow me to sign into that account. So even though the apps themselves store their *own* results, I can't aggregate them anymore like I can when I use the website. Also, both of the Windows 10 apps don't show my IP address in the results anymore, whereas the website does. If you're going to go to the trouble of writing these apps, please make sure you can do the same things that you can do on the website, or else why bother?
