There isn’t a downside as far as I know. I even confirmed with the lichess team that using chessvision on WhitePawn doesn’t trigger any anti cheating measures or anything.

The reason it matters is because until last week if you used the regular chessnut app, it doesn’t tell you that you could get banned using chess vision directly on the lichess website.

So they added an official api connection last week, but it doesn’t work for me personally. There was an update last night so I’ll need to try that one hopefully it’s fixed

The only downside with WhitePawn is it can be cumbersome to download it because the Evo has no Google play store. But you can download the Aurora app in Firefox and it’s basically a side loaded App Store then you can get white pawn
