If you're trying to get rid of the Apple Podcast pop-up, follow the steps below:

1. Open the Settings app on your iPhone or iPad.
2. Scroll down and tap on "Podcasts."
3. Look for the option that says "Sync Podcasts" and toggle it off.
4. Also, turn off the "Notifications" for Podcasts. To do this, go back to the main Settings menu, tap on "Notifications," find "Podcasts" in the list, and toggle off "Allow Notifications."

Remember, these steps will prevent your device from automatically downloading new podcast episodes and you won't receive any notifications from the Podcasts app.

If you're having issues with a pop-up in a specific app or while browsing, it might not be related to the Podcasts app. In that case, you would want to look into pop-up blocking for that specific application or browser.
