No install. No account. Public and anonymous. The link asks your agent for one report, nothing else. What it sends

Still happening. 1 report or thumbs-up in each of the last two weeks, down from 2 a week at the mid-October peak.

Agent cannot reach visible in-app browser: Browser is not available: iab. The in-app browser opens and loads pages, but selecting it from the Browser runtime fails while ambient context still lists an open tab.
