Why doesn't Telegram show notifications?

1. Add the Telegram bot "OhDearApp”
2. Copy and paste the full /start@OhDearAppBot ... command into Telegram
3. Press 'update' with your Oh Dear notification settings
4. Send test

From here you can enable/disable alerts on this channel for different events (e.g. site down, broken links found, domain issues found etc).

Remember to save your changes by pressing 'Update'!
