FR965 - Garmin Connect 5.21.2 - IOS 26.2.1 - iPhone 15 Pro
When using Sleep Score -> Timeline from the "in Focus" app list, I select an overlay such as "Respiration". When I make the selection the list of buttons "slides back" so "Breathing Variations" is again listed first. The Respiration overlay is shown, but its button is not highlighted nor seen in the viewing area.
Particularly weird: it works the first time after installing a new version of Garmin Connect. Initially the selected button will remain highlighted in the viewing area. The next day the bug returns.
