Well, I found this report(and several more) in various Resistance Telegram channels that I follow. In this case, the user was unable to see t.me/DDGeopolitics. If you are in the USA, you can try to check if you have the same message as well.

Also, this censorship is not new. In 2025, workers.org published this article regarding this: https://www.workers.org/2025/06/86197/

Many channels, ranging from @unity_of_fields to the official channels of many Palestinian, Lebanese and other resistance organizations, are blocked on the versions of Telegram downloaded from Apple and Google stores.

While the versions of Telegram downloaded from the website are still vulnerable to regional censorship — for example, the block on our old channel, @samidounnetwork, in many locations, that on RNN (@PalestineResist) in many areas, particularly in Europe and other regional blocks on Palestinian, Lebanese and Yemeni resistance organizations — they are better options than those on the App Store/Play Store for accessing important content.

Taking this into account, it wouldn’t be surprising if this censorship expands to Iranian related channels.
