Same, approximately. I got one literal grandma to use Jitsi, and all of my literal grandparents to use BigBlueButton, and the latter actually took effort. Jitsi is significantly easier to use than Zoom et al., requiring no account or anything but a browser even to host a meeting, and having an extremely intuitive UI compared to eg. Zoom, with eg. the "Raise Hand" button being a hand icon right on the bottom bar next to mute, etc. where there’s just empty space in Zoom, instead of buried under a "Participants" button. BigBlueButton is slightly less simple (eg. you need to log in to host, at least by clicking “Login with Google” or with Twitter or Microsoft) but both have worked flawlessly over dozens of meetings and been understandable to my grandparents.
