Anyone experiencing any of the below errors? I don't know what's related to M1 vs Big Sur

  1. When "Optimized battery charging" checkbox is checked, external HDMI monitor will not stay on if the lid is closed
  2. External monitor will not stay on unless the lid is open after the MBA is locked. The only way to fix is to disconnect/reconnect the monitor
  3. The "Optimized battery charging" checkbox rechecks itself after a restart
  4. When swapping between HDMI monitors, the MBA still thinks the original one is connected until I restart the computer
  5. Unrelated to Big Sur as it's a long standing issue, but why doesn't Apple support CEC for HDMI monitors so that you can control their volume from your mac?? PCs have been doing this forever!
