As someone who was frantically checking the portal last year, I have an educated guess of what the changes mean for those also freaking out about it. I noticed the changes on Tuesdays (which seemed to be when acceptance calls were made, if I remember correctly) in an older browser (one of the readily downloadable old versions of Firefox. I don't know if it's more readily seen by Safari on Macs, but I never noticed it in my up-to-date Firefox or Chrome versions for Windows 10). I also first noticed the error about three months before I was accepted (in November, and I was accepted in February.) I don't think this means I was already accepted 3 months before they bothered to call, I think it means they opened my file multiple times (which means it's not a guarantee of acceptance, just a guarantee that they looked at you.) I also know of someone who saw the same glitches using a similar alternative browser and never got accepted. I could be wrong though. But either way I wouldn't sweat over whether some glitch does or doesn't come up at a given time. It's a bit like reading tea leaves, and if my n=1 carries any weight, it certainly won't make you any less anxious whatever the glitch status is. Good luck to all!
