Hi David,
I recently created a new Strava account for my son and linked Intervals.icu with it and he only has 4 activities in 2 days. In the activities calendar and list view, it looks like Intervals is trying to fetch older activities but because it finds none it continues for ever (you probably are limiting the number of activities or weeks the tool fetchs before scrolling but for new accounts they don’t reach that number so Intervals continues to look for more.
