Why the file id, in telegram bot, not work after some days?
<p>I am using telegram API and create php telegram bot. For sending video file with <code>sendVideo</code> method, use <code>file_id</code> like <code>BAADBAADbwADhd7gCEpUooz4V5Q1Ag</code>. But after some days this <code>file_id</code> not worked and I have to upload this video file again. What is the problem?</p>
