Description

When DIUN skips a notification (e.g. on first check) the related log entry is shown only on a debug log level, which may be confusing. In my case I was trying to debug notifications (specifically Telegram), while they are completely functional. Switching to debug logs made me observe the true reason on why the notification was not sent.

Expected behaviour

Assign the "Skipping notification" log to the info level

Actual behaviour

The "Skipping notification" is only shown at debug level

Steps to reproduce

docker compose up -d && docker compose logs -f

Diun version

4.28.0
