Same here, mine was from a spam email that hadn't been caught properly by Gmail and was later removed. Really great article, didn't know about the 3 settings which would have stopped me getting the notification as not accepted.
Congratulations on launching, the professionalism and communication from these guys are second to none. Now to go find and read the Slack bot integration!
Looks very promising, sadly I cant get past configuring a new SQL Server data source (which does say Beta).
Points of contention-
First load using edge DataSources was not visible at the bottom right, had to access from User drop down menu and nothing happened
No error returned when trying to connect to a SQL Server type connection, just said Invalid database address with no further information about why. (default database wasn't accessible was the problem).
After getting past the connection screen, tables are arranged in a nonsensical fashion, not a huge issue but I would have thought alphabetical option at minimum.
Some tables don't preview, haven't dug into this further.
Once I selected a table it could preview, clicking NEXT did nothing.
