i am on adguard (premium) 4.10 nightly 2. nightly for years no. although there were some issues, not worth thinking about.
I think my problem was solved. Apparently, I was running version 4.6. After updating to 4.9, I have no issues anymore. It might have also been because I enabled watchdog.
AdGuard for Android 4.10, Release date: June 25, 2025 https://adguard.com/en/versions/android/release.html#version-41065 Edit: AdGuard for Android v4.10: New HTTPS certificate installation flow https://adguard.com/en/blog/adguard-for-android-v4-10.html
AdGuard for Android 4.10 seems to be running smooth here along with AdGuard VPN and Bitdefender. I'm liking this combo.
