Moen Flo integration - Today's water usage does not update always

Hello, I recently connected a Moen Flo to my HA, using the Flo integration. It brings in a few sensors, such as total water usage, water flow rate, water pressure. I notice frequently that the water usage (Today's water usage) does not update at night after I take a shower (around 10pm). In the app it will register the water usage, but in Home Assistant, it does not budge, and then at midnight Today's water usage does not reset to zero but it will start at how much I used the night before for that shower. For example, I use 100 gallon, take a shower that uses 50 gallon, then the sensor shows 100 gallon until midnight, then it drops to 50 gallons. The other sensors like flow rate show all the recent values.

Wanted to ask if this was normal behavior for the Flo integration, if it is a bug, or normal behavior.

Thanks!
