WeTransfer doesn't seem to be working for me. If I go to Options/Attachments I see it in the list of providers, but it has a yellow triangle with an exclamation point next to it. When I attach a large file to a message, I don't get the option to send the file via WeTransfer. Do I need to activate the account or something? I can't figure out how to do that if it's so. I'm using Thunderbird 78.6.0 (64 Bit) on Windows 10. I just bought a new PC so this is a new installation of Thunderbird. Everything else is working A-OK. I used to use WeTransfer all the time on my old laptop. Hard to find any information about this online. Thanks!
