Telegram bot setChatPermissions method not working

I tried to set chat permission for the pilot version of my bot using this url: https://api.telegram.org/bot<token>/setChatPermissions?chat_id=<chat_id>&can_send_messages=0 But I must try it almost 20 times until it really works and the 19 other times, nothing happens. Wondering I always receive this back even when it does not anything: {“ok”:true,”result”:true} What is the problem? Is it…
