Yeah… After a user here on Lemmy pointed out that the AdGuard app on mobile made a lot of strange requests to ads services, I gave it a try myself with PCAPdroid and seeing all thoses requests made by only opening the app made me think twice about AdGuard…
Removed all their services from my network and a happy piHole + quad9 user since !
Thanks for sharing your experience ! I was kinda interested for my new N300 if I should install promox+LXC-docker or promox+VM-docker !
Hearing you had a lot of issues and caveats makes my choice easier wihout even giving it a try ! So thanks !
