I have on a number of days this month seen Venus during the day.
It’s quite dim, comparatively, kind of like a night light in the distance - but it is, (or was three days ago) visible.
I used to catch it a lot a few years ago during daylight hours when I was active with my scope. It's actually the best time to see its various phases. It goes through a series of phases much like the moon does. But at night it glares too brightly to make out the phases, even with a telescope. During the day, as you said, it's comparatively faint. Perfect for observing the phases, IF you know how to find it. I usually find it first through binocs, then move the more powerful scope to it.
