The pre iOS 13 app wasn’t perfect, but this new version is a huge step backwards. They fixed some of the initial bugs, but trying to review detailed usage has lost a huge amount of functionality from the previous version. For instance, when viewing monthly usage data, you can only look at the last billing cycle (as opposed to recent data, like you could with the old app). Also, the old version you could review hour by hour demand charge for dates as recent as the previous day. This version won’t show anything but what your previous bill says. Absolute garbage.
Full disclosure, I work for APS. I’m ashamed.
