On the web version, when you delete a chat, the warning message includes the title of your chat, so you can confirm you are deleting the right chat. In the Android app, the title is NOT in the warning message, so there is a chance you delete the wrong chat. When you are inside a specific chat, and you delete from the 3-dot menu at the top right, yes, you can be reasonably sure you are deleting the correct chat (i.e. the chat you are in), BUT if you press and hold the chat title from the left menu tray (two-bar menu at the top left), you cannot be sure because the chat that is shaded/highlighted is not necessarily the chat you are deleting. One example: In the attached screenshots, I was viewing one chat, then I went to the left menu tray and I long pressed a different chat to delete it. The warning message comes up without confirming the title, and there can be confusion because the shaded chat is a different chat from the one I am deleting.
This will lead to accidental deletions, and since we have no trash folder (that is another issue), that would be a significant issue.
