It’s confusing not being able to see your last meter reading when submitting a meter reading as you don’t know if what you just submitted was taken or not. Even if it just says pending or something that would be helpful. I noticed afterwards the reading show up on the usage page, but I think it would be helpful to print them on the submit reading page as well.
Also if you submit your electricity reading the notification comes up saying you’ve submitted your electricity reading, if you don’t close that notification and submit your gas reading the notification still says you’ve submitted your electricity reading. The notifications should either stack or the electricity notification should be replaced by the gas notification as that was the last action you took.
Just little things to make the UX a bit better.
