Appointy calendar is intelligent enough to detect your screen resolution and automatically decides the best size for you. Sometimes when you as an admin books a new appointment it gets offset by a few seconds. This happens when your browser's default zoom level is greater or less than 100%. Please correct your zoom level to fix this minor issue.
To give you a clear picture, we have replicated the scenario on Google Chrome browser (see the attached screen capture). The bookings are incorrect due to the ZOOM level set to 175%. The screen capture gives you the tip to troubleshoot it on Google Chrome.
If your web browser is set to 100% and you are still facing any issue, please send us the following details:
1. Operating System
3. Version of OS and web browser.
Once we have the above details, we can investigate the matter for you. You can reach us at firstname.lastname@example.org.
Note: Please see attached screenshots for Chrome, IE, Firefox & Safari browser's zoom level settings.
