In the event dashboard, click the event app card

Then select the App Branding on the left menu.

In the right-hand side column, open the Splash Gif section, upload your splash image in gif format, in the resolution 1080\*1920 GIF upto 10MB.

The splash screen, or the launch screen,  is the first screen that shows up when the event app is opened. An animated splash screen creates a great first impression when your attendees launch the event mobile app.

Keep the gif duration to under 5 seconds. A long splash screen may frustrate attendees trying to enter your event.
