played mines on mobile and desktop then casino flagged session as duplicate device

Last night I was messing around with mines, tried a couple spins on mobile while my desktop session was still open in the background. Next thing I know I get a flagged session alert and it says “duplicate device” on my account page. Never ran into that before, and now it’s got me paranoid. I do hop between devices a lot since my work setup is right next to my main rig at home.

I’m not running any bots or scripts or anything like that, just genuinely moving from one device to another depending on where I’m sitting. Anyone else run into this or know how strict these sites actually are with sessions? I’ve read about other folks getting locked out or even bonus bans but wasn’t sure if that’s normal or just bad luck.
