Feed not updated when reloading manually

1. Environment

• Device: Motorola Edge 40
• OS: Android 14
• APP: 0.11.1

2. Describe the bug

The RSS feed I added to the app does not update its entries when reloaded manually from the app. It also doesn't update in the background .
When pressing the RSS link from the context menu of the feed it correctly displays the updated information, which however is not mirrored in the app.
After cleaning old articles, a manual update will work as expected and parse the new information into the app.
I should test if the app updates the feed in the background when the feed is empty

Expected behavior:

The app should update its entries both manually and in the background to reflect the latest state of the feed, regardless of the presence of old entries.

Steps to replicate the bug:

• Add the following RSS http://scioperi.mit.gov.it/mit2/public/scioperi/rss (lists announced strikes for transport services in Italy)
• do not delete all the entries in the app
• wait until a new strike is announced and the RSS updates
• reload the app manually to see no new updates in the app

Reproduce the issue with the provided RSS URL while existing articles remain, then trace the manual and background refresh paths. Confirm that both paths detect and display newly added feed entries without requiring old articles to be deleted.
