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 declaring that it accepts feed content critical
This application is requesting feed content from websites but doesn't indicate that it accepts content specifically designed for feeds.
Why it's a problemWebsites are likely to block the application from accessing their feeds due to the app not being specific or entirely clear about the content it accepts.
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 itThe application should explicitly declare a format commonly associated with feeds using the Accept header.
