URGENT: RSS Feed - Check if already stored in Google Sheets

Hi guys,

would be really glad if anyone can help me. Tried out many things but it doesn’t seem to work. The workflow is pretty straight forward. I have multiple RSS Feeds which I split in Batches and in theory I want to check the latest article if that’s already stored in my Google Sheets - if Yes then take on the next Batch (next RSS Feed) - if Not then append the article to the sheets and then take on the next Batch.

Does not take the latest articles even though I selected “execute only once” - it randomly took 2 articles from the middle of the RSS Feed Return. Don’t get that.

Any help is highly appreciated.
