Yeah, the signage is updated. I wasn't able to figure out how to upload a picture via StreetComplete (sorry, I'm new to this) but I took a photo at https://imgur.com/a/hPoNo6C. I actually happen to work at Plaid so I can confirm that we're the only ones in the building since Atlassian moved out back in 2019.

If there's supposed to be a way in StreetComplete to add photos to a location, let me know and I'll research how that works, there's probably something I just overlooked in the interface.
