Norton Private Browser - broken website (Better Gym UK)

fwiw ~ as test:
Norton 360 and Norton Browser on-board.
Norton Browser Application and User Data installed (current user) default location \AppData\Local
Norton Browser not default browser
Norton Browser not set to launch automatically when computer starts
Norton 360 Product Tamper Protection default enabled
fwiw ~ as test:
call NortonBrowserUninstall from \AppData\Local






my as test: this time went easier than I remember last time. I must have had other Norton v24 glitches at the time.
maybe, Norton Browser installer/uninstaller improvements from last time/last year?
