The new web versions of the messenger are marked with the letters “K” and “Z” and you can check the version K Version Here and version Z Here. According to the Telegram team, both versions work equally well on both desktop and mobile devices.
When asked why there are two versions of the web app, the messenger team replied that they believe in internal competition.
However, not all Telegram features are implemented in both web apps at the moment. For example, they don’t yet support secret and voice chats, audio and video calls, the media editor, and the option to use multiple accounts at the same time. The full list of features not yet implemented in the web versions of Telegram is available Here is Here.
Furthermore, Telegram has released an independent app from Google Play in the form of an apk file, which will be updated more often than the Google Play app and will have fewer restrictions. It can be installed from the telegram.org/android page, ignoring the app store.
Apparently, the application contains materials that are blocked in the Google Play and App Store versions, especially pirated and adult content.
