Signatures in New Outlook for Mac have disappeared

I want to point out some other errors also with Outlook that though not as serious as the Signatures completely disappearing, still an issue.

1. Why do "sent" items stay in the inbox and go on top of the email? I don't want to sent my own sent items in the inbox, this is like gmail system and I HATE it. I cannot easily see what emails I need to address when my own sent emails are showing in inbox.
2. Now emails I have addressed in my inbox I take them to a folder do not "move" to the folder, but rather "copy" - resulting in leaving the email still in the inbox. No idea what this also would be of value and makes sorting the inbox trouble yet again.
3. Deleted items and Junk Mail. you can delete items from both of these but "ghost" emails remain, you cannot open, view or delete them, but they still "show" in the junk and trash bin. Yet another bug.

Again all these 3 points are a not a deal breaker like Signatures, but nonetheless not working how a professional email should work. When will MS have ALL these bugs fixed? It states on this page here: https://support.microsoft.com/en-us/office/microsoft-365-office-2021-and-office-2019-support-for-apple-silicon-c55b603e-14a6-4b69-bdc0-2bb4c9a36834 you don't need a separate download or M1 chip, but actually you do. Zoom has a separate download for M1 chip Macs - maybe Outlook and other MS products should also?! If MS states that it doesn't need then it should deliver on a bug free app.

You "believe" the Mac team is looking at it? Can you confirm? Is there a KB article that we can follow or a ticket number we can reference?

Really surprised it's taking this long for a fix guys. Horrible in fact. One of the major reasons I switched to Apple of MS 16years ago was the constant bug issues with MS products -seems to be their "legacy" continues! No one at MS replying or checking this thread??

I didn’t have this issue when switching to legacy all works well. During the switch though I was prompted to add my account like in a new installation…

I've had the same issue, but I found something that might work. I realized that my Task Pane was turned off, so I clicked View + Task Pane, and suddenly my signature (well, one of them) was available. I'm not sure if that was coincidental or if (for some weird reason) that activates the signatures, but so far it works. Fingers crossed, and hope to see a fix and a reply from Microsoft someday!
