Does anybody know what this means when I try to use good lock?

Hello 👋 @JustSomeRandomGuy 

The Samsung Forum Team will be along soon to moderate your upload to see if this does not contravene the community rules. 

Until then can you perhaps elaborate to see if we can help 🤔 

If i can be of any further help please don't hesitate to ask  😎

Basically it means that the version of Lockstar you are trying to use is not compatible with OneUI7 beta.
If you go to Samsung Store it says v7.0.00.14 is compatible and will work with UI7. If you check in your Lockstar app under the three dots, then ″About″, you're probably on v6.1.00.18. Even if you try and uninstall it, then download it again from the Store, it will still install v6.
I've reported it to Beta Feedback and GoodLock, but I expect they're busy and it will get fixed shortly!
I know I can 'side-load' this from APK Mirror, but it's not a route I want to follow.
I should add, I'm using an S23U, and if you're on an S24/25, it may be a different reason.
