Ring using mobile data AGAIN

I saw a previous post saying how the app was using mobile data instead of wifi. Someone reported they updated to version 3.48.0 and the issue was resolved. I am on version 3.52.0 and currently experiencing this problem.As soon as I open my device (wired doorbell) my phone switches from wifi to 4G. As soon as I close the app it goes back to wifi. Funnily enough, despite having good signal I get a really jittery video. Has the previous bug been re-incarnated?Has some junior dev badly merged a branch?
