How to run a firewall and an AdBlocker on a non-rooted phone at the same time? I have a non-rooted Android phone and would like to use both a Firewall and an Adblocker at the same time. How can I do this?

I could only find Firewalls and Adblockers for non-rooted phones that use use VPN with only one VPN connection being allowed.
You can use adguard for this purpose which has the capability of both a firewall and an adblocker. It sets up a local vpn for non rooted phones. It also has a proxy mode. ( inorder to use with other vpns).
