We're excited to let you know this suggestion has been implemented! Today we released an update to the "Time scale in minutes" field on the Calendar Preferences page, adding some new options that are available to select. You'll now be able to set appointments in increments of 1 minute, 10 minutes, 35 minutes, 40 minutes, 45 minutes, 50 minutes, 55 minutes and 90 minutes in addition to the options that were available prior to this release.
Thanks for your feedback on this suggestion! If you have any questions or feedback, feel free to reach out to our support team at support@theranest.com.
