Gen 1: Weather Intelligence skips aren't recorded

I have a Gen 1 controller and the rain skip on it seems to work as it should. When rain is forecasted, or when it’s raining, it skips scheduled irrigation on the Flex Daily schedule that I’m using.

But, the app never records Weather Intelligence skips. It always says zero even when it has indeed skipped. I also never get alerts.

Any reason why this is happening and how can I fix it?
