Well, a pleasant surprise this morning. 2020.12 got installed a couple days ago, with no effect on rated range or the model designation on the MCU. This morning, the MCU had changed to “Long Range Plus”, and rated range at 100% is now 391, as shown on the charging slider on the app. Definitely was not that yesterday. I’m now charging to 80% and we’ll see what the 80% rated range will be...
