So – it does not mean anything bad about your case. Hopefully the 2NLs will be replaced within a few days, but those of you with June interviews will already know that date and can arrange medicals and so on. So, no need to panic!
Now – because of DV2020 the site will be overwhelmed by people checking for the next day or so (after noon USA Eastern time zone today, May 7). So – no need to worry about that either – it is expected.
Remember – RELAX, be patient. Don’t freak out….
