Undo send is extremely useful, but after the last major update, the undo send feature button is only available for almost exactly ONE SECOND, even though I have it set for 10 seconds. It works fine on the desktop but not on iPad or iPhone. Please RESTORE this extremely valuable feature.
I posted this a few days ago, and a proton admin declined my idea. Instead, the admin posted a note about how to implement this feature in the program settings. The admin obviously did not read my post carefully. I already know how to implement it. It just does not work.
