Blake_ASUSDear Blake, waiting does not help. I tested many scenarios, but the only way to limit charging below 100% is to run My Asus, set to a random limit, and then back to Maximum lifespan mode.
Please kindly understand that My ASUS is an APP, which is only functioning when you enter or working under Windows system.
So there is a time period between booting up to entering OS, the APP can't help to control the charging.
This does not affect regular daily usage.
