Requests are unidentifiable severe
Feed requests appear to be associated with this app but can't be accurately identified.
Why it's a problemA feed reader that can't be identified is often unfortunately used in ways that are severely abusive to a website, either intentionally by malicious users or unintentionally by its users who may be unaware. Since this application is unidentifiable, there's no way to validate its requests and mitigate any potential abuse.
What it means for usersWebsites are likely to block or severely limit this app from their feeds, causing feeds to behave unexpectedly or not work at all.
How to fix itThe application or its usage needs to be verified, which will remove any limitations or restrictions, and feeds used in the application will be much more reliable.
Not using updated feed locations critical
When a feed from a website is moved to a new location, the website informs the application where the feed has been moved to. However, instead of using the new locations of feeds, this application continuously tries to request feeds from their old locations.
Why it's a problemIt causes websites to use more computer resources than necessary to forcibly redirect the application to the rightful place over and over again.
What it means for usersFeeds will stop working or become fully inoperable when a website blocks the application due to this behavior.
How to fix itWhen a feed has been relocated to a new URL, the application should use the new URL and cease attempting to request feed content from the old one.
