I'm still having trouble updating my Samsung Fold 7 to the latest One UI 8.0 from the One UI 8.5. Could you tell me when the update is coming?

I am using a Samsung Fold 5 with dual SIM functionality, and I am encountering an issue.Currently, when primary SIM 1 is activated, it utilizes mobile data, but I require SIM 2 to handle mobile data. Please advise on how to configure this.
