[Bug]: Watchtower only logs startup messages, no container check/update summary

[MISIKEX]

Bug Report Checklist

• I checked existing issues and found no duplicates.
• I have reviewed Watchtower's documentation and confirmed compliance with documented configuration specifications.
• I have restarted Docker, re-pulled the latest image, and confirmed that the issue persists.

Bug Description

I am seeing a confusing logging behavior with Watchtower 1.14.0.

Watchtower starts correctly and logs only the following messages:
Watchtower 1.14.0 using Docker API v1.51
Using no notifications
Next scheduled run: 2026-02-01 20:13:16 CET in 11 hours, 59 minutes, 59 seconds

No log lines are printed about:

• checking containers
• number of containers checked
• number of containers updated

Expected behavior

I would expect Watchtower to log a message indicating that a container check was performed, e.g.:

• “Checking X containers”
• “Updated Y containers”
• or at least “0 containers checked”

Steps to Reproduce
