Several emails in my Earthlink Webmail inbox online received between 6:03 am and 9:21 am PST 2/21/2022 did not download to Thunderbird when I clicked on "Get Messages." They came from 2 different sources from which I have received and downloaded email many times before with no difficulty. Since then I have received and downloaded emails from these same sources, so there appears to be no ongoing problem. Earthlink tech support said there was nothing wrong on their end and my version of Thunderbird is current. This has never happened before in many years of both Earthlink service and using Thunderbird. ??? (No jargon, please, as my tech knowledge is seat of my pants.)
