Ongoing unexpected charges after installing an astrology app

Hi everyone!

I installed an astrology app - Nebula and that looked really nice and everything worked great at first smooth design calm interface, no issues at all but after a while i started noticing small payments showing up on my card that I didn`t expect..

At first I thought it was just a delay or some regular update but the same thing kept happening again. It`s been almost two months now and i still can`t figure out where these charges are coming from or how to stop them

I`ve already checked my subscriptions in the settings and nothing shows up, even thought the charges on my card are from Nebula. Has anyone dealt with something similar before? is there another place were recurring app payments might be listed or managed?

Just trying to understand what`s going on and how to prevent more charges
