Thank you, we're glad to hear you enjoy the app! If you’d like, you can change your review to 5 stars (a positive rating).

We're sorry that you're having a poor experience with the app. Telegram may show some non-invasive sponsored messages in large public channels, to help keeping Telegram free for everyone. Any other content shown in channels or groups is under the responsibility of the relevant owners. Sponsored messages are not shown to Telegram Premium users.

It sounds like your WiFi or mobile data provider is throttling your connection to Telegram. Enabling a VPN or proxy service on your device should increase upload and download speeds for you.

We're glad that you're enjoying Telegram. Thank you for your review!
