It actually has everything to do with telegram. The message you received is in a secret chat. That's why you have no preview. And I even recreated it here and someone had a similar question on Twitter
Hi @W3nD3l, I hope you're doing well.
As my partner @SJohnson said, this is not a bug or OneUI issue. This is the result of a "secret" chat message. Me and him just tested both regular and secret chats for the sake of finding you a correct and proper answer.
We hope this helps!
I know how to ise telegram properly I've been using it 3 years now and the issue its the software not telegram u can see clearly on that image that the toggles don't appear 🤨🙄😒
They don't appear because we just used it in secret chat as we stated. It's not a software issue. Whoever you are texting is in secret chat
