Since recent update, Active Hours detail just spins

[phs3]

I'm on 3.64.5 for Android (3.65 is allegedly available, but does not show up in Android Play).

If I tap the circle of active hours ("n of m hr / 250+ steps per hour") I now get a display with two busy spinners and two buttons, "Active" and "Still", neither of which does anything. Nor do the spinners ever stop spinning. I can go Back.

Am I the only one seeing this? Seems borked. OnePlus 7 Pro, fully patched.

3.65 is only available for Android 10+.  Why is that?  Not much good if you are on Android 8.

3.64.5 (previous version) is crashing (app stopping repeatedly) and the graphs are rubbish.  Had to Force Stop the app and stop using it.

I'm on Android 11. Still no sign of it in Play Store. At least it's not crashing for me!

Well, now I have 3.65, but it still just spins. Nobody else is seeing this? I've cleared cache and data for the app and force-stopped it, logged back in and same result.

Can someone who isn't having this problem maybe post a screenshot of what you see when you tap on the "Active hours" tile?
