New blocker needed

Hello,

I have realized through trial and error (and relapse) that my current p blocker has some glitches:

- the app that I use does not work when I connect to certain wifi networks. I e-mailed the company/app and they told me it has something to do with the wifi network's VPN connection.
- the app will continue to not work if I keep the p website open on my phone after I have left the network. For example: I connect to a wifi network, open up p pictures or videos, keep the tab open, leave that network, and then still able to continue searching for more/new p now using my data instead of just being able to access p in that specific wifi network.
- if I dig hard enough, I can find p pictures on an already restricted reddit.
- aside from connecting to certain wifi networks and the occasional photo on reddit, the app works very well and has been very helpful to me.

I know the simple answer here is to be more disciplined, but it would really help to have a more reliable blocker. I am currently using a Samsung galaxy S9. Any recommendations would be appreciated.

Thanks!
