Instagram quietly drops end-to-end encrypted chats

Does anyone know if they’re unencrypting chats that already happened? Like my chat history? If so that’s fucked up
If they can, then it was never e2e encrypted.
Well e2e encryption is never private for the entity contrilling the endpoint. Instagram could push an update which decrypts and uploads your past chat history. Of course they’d only do it for your benefit so you don’t lose any data /s
