Why are no free times shown?
Usually no cleaner works that day, or everyone is busy.
Free times come from your cleaners' working days and their other visits. Check that:
- at least one active cleaner (or someone with Also does cleans) is in Setup → Team;
- that cleaner has the day ticked in their working days;
- they are not already booked at that time.
In the office you can still press Book anyway to book over a clash.
