App Made purchase within app that triggered my web browser to block two pop-ups.

I had an app that had expired its free trial, and it asked me if I wanted to renew from within my iPhone (it is all Chimera jailbroken). I had my computer next to me, they are both connected to the same wifi AP. But iTunes was not open, and I wasn't using my computer at the time or on any apple web sites.

I didn't want to purchase the app, but it asked me to touch the home button to authorize the purchase. I instinctively pushed down on it thinking it would background and then I could do a close-out, but of course it read my print and bought the app. Oh well.

But the second it registered my print, my browser on my computer running Windows 10 had two popups, that were blocked by my content filter. Neither were related to the app I was using, apple, or anything that could relate to what I had just purchased.

It was just odd. iTunes wasn't running, though its probably got services running in the background.

What the heck happened? Why did purchasing an app trigger something to go out through my web browser?

Or was it just a wild coincidence by chance?

I should also clarify that I meant the device was jailbroken using Chimera and in a jailbroken state, but the app that made the purchase was an Apple AppStore app on a free trial that had expired called HMA VPN. That's the app I made the purchase through that caused two pop-ups in my browser the second it read my print.
