I am using the Zoom team chat on the PC app. A few days ago, I used the feature to add tabs at the top of the channel and added an existing document as a tab. However, yesterday that tab stopped working, and I can’t delete it. When I tried adding the same document again, it worked fine, and I was able to delete the new tab. I want to remove the non-functional tab, but I can’t, and it’s causing some trouble. Has anyone else encountered this issue? Do you know the cause or any possible solutions?

私はPCアプリでZoomのチームチャットを使用しています。数日前、チャンネルの上部にタブを追加する機能を使って、既存のドキュメントをタブに追加しました。しかし、昨日そのタブが機能しなくなり、削除もできません。同じドキュメントを改めて追加してみたところ、それは正常に動作し、新しく追加したタブは削除できました。機能しないタブを削除したいのですが、できないため困っています。同じような問題を経験した方はいませんか？原因や解決策が分かる方はいらっしゃいますか？

My company have enabled "Advanced Chat Encryption" for our Zoom messages. This adds a little 'lock' symbol above the message field that says:

"Chat content is Advanced Chat Encrypted. However, this chat's metadata (such as the chat's name and chat members' names) will still be viewable or editable by account owner, account admins, and others designated by the account owner."

This pop-up comes up every single time your mouse cursor passes the icon. This is extremely frustrating as I have multiple monitors set up, with Zoom on my right-most monitor, and my cursor very frequently passes this icon. 

Every time I go to write a message, or move my cursor away from that location, the pop-up message appears. The issue is that it does not dissapear unless you click elsewhere in the Zoom window. 

As per the image attached, you can see that the pop-up covers a large portion of the text in the chat window, which means that if I move my cursor away from Zoom and pass the icon without realising, I have to click back into the window to make it dissapear. 

The pop-up should dissapear when you are no longer hovering, require a click to see it in the first place, or the icon should be moved to a different location such as under the "More Info" button at the top right of the chat window.
