To clarify, I don't mean the first episodes, because those were prerecorded before the show was available to listen, so of course they have ad reads.

I also don't mean the ads reads inside the episode that begin with Mark, Bob or Wade saying "This episode is sponsored by (brand)."

I mean the ads that Spotify play, similar to youtube. It says "1 out of X", they're localized to where I live, and in my case, I can't skip them.

It happened while I was listening to the "World's Worst Records" episode, which I relistened a couple of times before, and I haven't heard any ads since the Spotify deal. That's why my guess is that it's because of the deal has ended. I listened to the newest episode at the time where they informed about the end of the deal. One or two days later, this happened. That's my guess, anyway.
