Hello, if at all possible it would be great to have the ability to add support for custom/user CA certificates stored in Android. This would allow AdGuard to filter applications with the HTTPS Filtering option enabled allowing more advanced protection. It would also allow for NextDNS' custom block page to not cause errors in some applications resulting in lots of error messages. This is especially a big deal when I have shared this application with others in the past and the ad blocking list doesn't always get all of the ads and creating your own list is too much of a hassle for most people.
