Upstairs activities > blank page

Hello,

after last update of garmin connect web, the upstairs activities show only blank page. If I click on the upstairs activity from all activities list the page starts loading, it shows for a split second the page but then the page is blank. I managed to grab screenshot what is seen for that fraction of second. I also noticed that there is error in browser console - attached is log from it. This seems like page error on server side. I have tried it with 3 browsers, clear cache and incognito mode but all 3 browsers failed to show the page.

Note that 'style-src-elem' was not explicitly set, so 'style-src' is used as a fallback. The policy is report-only, so the violation has been logged but no further action has been taken.
