I was at my first post-Covid sales conference a couple of months ago and this is the only way that contacts was shared.

I've been thinking about getting a QR code sticker that I can stick to my phone that has my LinkedIn url for easy adding.

I never log into LinkedIn on my phone, and I would never in a million years install their app — OTOH it’s easy enough to type in a LinkedIn URL when I get to my home computer and an isolated browser instance.
