RSS feed doesnt refresh properly

Hey there,

I was testing out the RSS feed event source and came across an interesting issue:

Check the following RSS feed:

When executing this in pipedream (every second) the system shows several events the first run but every single run after that, no new events are detected. Only very irregularly something comes through, indicating a big delay between the publishing time and the rss feed coming through to pipedream. Checking the actual feed through the link, there definitely are more events. What is happening here?
