When I compose a reply in Apple Mail, my iCloud addresses disappear as sending options
This has been an odd behavior in my Apple Mail on Ventura for the last several months - when I reply to an email sent to my iCloud (mac.com) address, the reply address changes to one of of my non-iCloud addresses, and I cannot see my iCloud address when I look at the popup in the "From" field.
When I go to Settings>Accounts, the iCloud account is there, but the Email Address field is blank. Refilling that via "Edit email addresses" re-enables my iCloud address in the "from" field of my newly-composed email reply.
I have no idea what is causing this glitch. I have an iPhone and an iPad linked to my iCloud account. My Mail application seems to be working properly otherwise. Is this a known issue that may be corrected in Sonoma? I would be happy to share my system logs with developers.
Thanks,
Robert
