I can't enable always on vpn

Phone and app details in attachments

I need the Blokada version 4 because it allows me to use clean browsing dns.

Blokada 5 does not allow me to input a manual dns nor does it support cleanbrowsing, which I need.

I was able to enable always on vpn with Blokada 5 but I cannot enable it with Blokada 4.

I follow the images below but there is no vpn created and nowhere to enable vpn permissions.

Problem fixed after restarting phone.
