As I understand it, this is not about android notifications but about preview of message that is replied to being static and not linked to the original message. I can confirm that this doesn't work on android but on tdesktop the preview changes when original message is edited.
I have a problem ,some messages appear again after we delete . This deleted message reappear problem comes even when we clear chat and open it again NB: Its not a problem with all messages but some messages please fix this
I fixed it
In the Telegram for Android v7.4.2 (2227) arm64-v8a when a message is edited, "in reply to" preview stays unchanged. But when we go to the dialog list screen and go back to the dialog where we changed the message, the message is updated in the "in reply to" preview.
