I reported the earlier portion to support by email but am adding a little more information here before any response from support.
FWIW, this also happens with other versions of the App (iPadOS and app-web) and with another grouping of time (clicking on Min and then up to see selector and left arrow to go back – shows data for 1:26 AM when time is currently 8:26 PM Eastern). The data appearing for a time appears to be the data which should properly belong hours earlier, for example my garage shows usage (my EV charging) at 9AM and 8AM when car had been gone from garage for hours.
I am also having trouble navigating back in time very far, for example click Hr then left arrow a bunch of times (or use slider all the way to the left) won’t go back further than 11/02 10 AM right now (at 8:30pm Eastern 11/03). I apologize if that is normal but I think it is bug.
