River 3 Plus needs firmware update?

I have a river 2, a river 3, and a river 3 plus.

If I set the discharge limit to 80% in the app, then the river 2 and river 3 discharge down to that limit and stay in AC pass thru mode.

However, when I set this on the river 3 plus the state of charge (SOC) just stays at the default of 100%. It won't draw down the SOC under the AC load - it just stays in AC pass thru mode.

I mean I can manually pull the wall plug and discharge it down but that is for the birds! I like being able to use the discharge limits to for the units to manually cycle them for long term use (as per the manual) I wish they would automate this when in AC mode / UPS stand by usage though.

Anyway, the River 3 Plus unit needs a firmware update to fix this behavior so that it matches the other units / expected behavior.
