Why wasn't the post deleted from Telegram?

In Telegram, a post can only be deleted within 24 hours of its publication. If this period has passed, it will no longer be possible to delete the post through the service — it will have to be deleted manually.

For example: if a post was published at 2:00 PM, it can be automatically deleted until 2:00 PM the next day. If you set the deletion for 1:59 PM, there is a risk that due to a slight delay, the system will not have time to perform the action, and the post will remain. Therefore, it is better to plan the deletion with a small buffer — for example, at 1:50 PM.
