Agree 100%. It has been over 1 month and not sure if/when the ability to add notes to the standard calendar for open/blocked dates will be back. You can only add a note to a reservation on the standard calendar currently.
In the meantime, Hosts have turned on Professional Hosting Tools and used the multicalendar to add notes. The multicalendar is only available on a desktop computer however. The notes can then be viewed on the standard calendar, but not edited there. You can edit notes on the multicalendar.



Another option is to create your own calendar (Google) and sync it to Airbnb. The issue there is the reservations dates are off by one day.
