We have deployed a new way to send Telegram notifications using an official Bot and Telegram groups, details may be found here: https://help.ubidots.com/en/articles/4333594-events-telegram-notifications

We have deployed a temporal patch and the messages are being delivered by Telegram. We will be monitoring the solution.

We were able to deliver notifications again at 05:00 UTC, but at 09:00 UTC Telegram again began to ban our notifications requests, we are looking to possible ways to solve the issue

Telegram is still banning our notifications requests, we are looking to possible ways to solve the issue

Some of our requests to deliver messages are being rejected by Telegram. Because of this, Telegram is not delivering alerts triggered by our events engine. The Dev team is looking actually possible ways to make Telegram to deliver alerts again, without an ETA to solution as this is something related exclusively with a third party app.
