My service provider is QX.net which uses Magic Mail web email. I have Firefox 115.ll, 64 bit. I have Thunderbird 115.11.1, 32 bit. The Magic Mail on my Server shows 253 unread messages. I have identified some of those 253 messages in my Thunderbird folder and they have been read, and are shown as read in Thunderbird. There seem to be 3 different dates involved. This is a concern as it is unacceptable not to receive all of my messages. Please advise what I can do to address this so that I receive all my messages and so that when I have read them they are shown as "read" in Thunderbird and in Magic Mail. Thank you so very much for any help.
