For me it was "Your browser is not compatible with Notion." on Android with Hack's (hacker news client) built in browser which is I guess just a stripped down Web view
For me it was "JavaScript must be enabled in order to use Notion" (I'm a NoScript user). But it had already redirected me to another domain to show this page. How am I supposed to enable JS for the actual domain of the page? I have ways of course, but it seems like notion is deliberately flipping the bird to people like me...
For me it was perpetual loading spinner.
in the meantime surely plenty of telemetry being ingested.
