Thank you for reaching out to us here in the Community.
We'll be happy to explain a bit more about this. Spotify gives the podcast hosts the option to choose if they would like to have a dynamic ad slot in their podcast.
You can find more info on this here. We understand that many of the creators that you're listening to seem to be using that option but that is not something Spotify can control - it's up to the individual podcast owners if they choose to have that type of ad in their content.
Hope this explains the situation. We'll be here if you have any other questions.
Take care 🙂
