I haven't seen this new annoying AI behavior because I use IMAP to access my GMail. After reading this post, I decided to backup my GMail inbox, which is something I've never bothered to do because it's mostly a secondary backup that I rarely use.

So it took a few minutes to finish copying all of the ~1,500 messages or so, and then I went to verify that I got them all. For some odd reason, GMail doesn't let me copy (at least via IMAP) any messages after 1/17/2024. It had no trouble copying everything older than that, dating back to May of 2009. I tried copying just a single message (from last week) and it silently fails every time. I can view the message via IMAP, but I cannot copy it.

Has anybody else seen this?

Update: It seems to be an issue with my mail server because I was able to copy the remaining 205 messages into a local folder.
