I completely agree with you. It seems the Unraid team is focusing on changes that confuse users. In version 6.12.10, which I’m currently using, the Telegram.sh script has been updated. There's no need to add a minus sign anymore. Simply enter the chat ID numbers in the /boot/config/plugins/dynamix/telegram/chatid file—no spaces, no minus sign, just the numbers. That’s all you need to do.
