auto-resignation glitch on his side that made me lose unfairly


Your description sounds like you were actually the one that got disconnected.

i considered that, but my connection bars were full, so it doesn't seem likely, to me at least, rather the screenshots I have show that his game timer didn't zero out for a whole 2 minutes, maybe even longer. Plus, even before the auto-resignation timer finished mid game, It still wouldn't resign the other guy. I'm not sure if that's what it looks like with bad connection, but it didn't seem exactly like the other cases presented by the virtual support assistant. (for some reason it's not attaching my screenshots here...)

The connection bars don't necessarily mean you were connected to the server. It's possible the client code wasn't updating correctly.
I'm pretty sure I found the game yesterday and it showed you didn't move for a significant amount of time after your opponent's last, which certainly indicates you were disconnected from the server process.
