As a direct report, you can change the time of your next 1:1. To do so, start by clicking on "Plan 1:1s" on your Home page and select the 1:1 event.
Please note: if your 1:1 is synced with your calendar, you must change the time of your 1:1 within the calendar, which will then update the time in Lattice.
Step 1: Once you select the 1:1, click on the date of the upcoming 1:1.
Step 2: Select the new time for your 1:1 and hit "Save Time".
