Emails from email@example.com have stopped arriving
I have 2-step email verification for Roblox using my comcast.net account.
It had worked a few times prior where I would tell the Roblox website or app to send a verification code to my Comcast account, but now it is no longer arriving, so I am unable to access Roblox at all.
I have tried this from the Roblox app, different browsers and nothing works.
It is not in my Spam folder. Roblox support claims innocence. Is firstname.lastname@example.org being blocked?
