I was a user on Telegram from India.
Telegram is not sending text messages because I don't have a premium account. And many features are locked in premium.
Currently, Telegram doesn't allow users to create or log in to accounts via third-party apps. Also, I need an official telegram (a must from the Play Store). (Not even the apk from their own website.) To receive a login code.
Do you guys ever feel that telegram has become so much worse?
That's inconvenient, I admit.
There's a certain philosophy saying that secret chats not being portable is more secure. That means you're not exporting the secret keys to multiple devices. I realize signal achieves this by signing the secret chats with multiple keys instead of passing the key around. It does reduce your risk surface.
