This is a bug, right? Or am I missing something obvious? The previous moisture balance (PMB) from May 11 does not carry over to May 12. This is the same for all my grass zones which are all on Flex schedules. It looks like the Irrigation+ for May 11 is being ignored in the May 12 PMB result.
I had something similar last month, was due to a personal weather station sending incorrect data. Not sure if that's the same here, but could be worth checking. I switched from a home station to the local airport and that fixed the issue.
