How to change default start page for my daily summary to always show the current date...not my first ever activity date
Do you use a bookmark to get to the daily summary? Check the URL. It probably got the date in it.
Use this URL instead https://connect.garmin.com/modern/
In the settings you set Daily Summary as your homepage and you will end up on the correct page with the correct date: https://connect.garmin.com/modern/settings
