I have AdBlock installed in my browser and it's on for any and all ads to be blocked, but since Aternos is so obnoxiously consistent with its messages to turn it off, I decided to do so for the website, however, I still have to wait seconds with every time I switch a tab and still get messages under the ads themselves about me having it still on.
The dev team should really look into fixing their Adblock detection code, as, clearly, it's falsely detecting or not detecting if it's even operating.
If this is normal behaviour, I might as well leave it on if having it off makes it worse.
