Google Analytics 4 have told us:
On July 1, 2023, standard Universal Analytics properties will no longer process data. You'll be able to see your Universal Analytics reports for a period of time after July 1, 2023. However, new data will only flow into Google Analytics 4 properties.

Is everything sorted and I’ve just done it wrong on my GA?
