Every time I turn on my Mac, Adguard fails to block ads despite the fact it's running and turned on - there's the logo in the menu bar, which when clicked shows protection is enabled. To fix the issue, I have to quit and relaunch Adguard (and if I've opened Safari, I have to quit and relaunch Safari too). After this, adblocking returns to normal. I'm running the latest version of High Sierra and Safari. In Adguard, all relevant filters are enabled. I can't see any reason why this should happen, except maybe me using Cloudflare DNS - I read certain DNS servers can cause issues with Adguard. What I do know is it's very annoying having to relaunch Adguard every time I log on. Does anyone have any thoughts or suggestions for how I could fix this? Thanks.
