Weather Intellgicence Plus loses historical precipitation data

WI+ correctly identifies precipitation for today and forecasted precipitation for the future. However, it loses precipitation data for prior days.

For example, we had about 1" of rain yesterday. And yesterday when I looked at the controller data, it correctly identified that we were getting about 1" of rain. But when I look at the controller data today, it lost track of yesterday’s rainfall and doesn’t factor it into the overall soil moisture (says overall precipitation was 0 for yesterday, but still correctly identifies precipitation for today and future days).

How can I fix the issue?
